c01f381545 ALSA: hdsp: Break infinite MIDI input flush loop
The current MIDI input flush on HDSP and HDSPM drivers relies on the
hardware reporting the right value.  If the hardware doesn't give the
proper value but returns -1, it may be stuck at an infinite loop.

Add a counter and break if the loop is unexpectedly too long.

b2aa4f8069 ALSA: rme9652: Fix the missing snd_card_free() call at probe error
The previous cleanup with devres may lead to the incorrect release
orders at the probe error handling due to the devres's nature.  Until
we register the card, snd_card_free() has to be called at first for
releasing the stuff properly when the driver tries to manage and
release the stuff via card->private_free().

This patch fixes it by calling snd_card_free() manually on the error
from the probe callback.

43d35ccc36 ALSA: pci: rme: Fix unaligned buffer addresses
The recent fix for setting up the DMA buffer type on RME drivers tried
to address the non-standard memory managements and changed the DMA
buffer information to the standard snd_dma_buffer object that is
allocated at the probe time.  However, I overlooked that the RME
drivers handle the buffer addresses based on 64k alignment, and the
previous conversion broke that silently.

This patch is an attempt to fix the regression.  The snd_dma_buffer
objects are copied to the original data with the correction to the
aligned accesses, and those are passed to snd_pcm_set_runtime_buffer()
helpers instead.  The original snd_dma_buffer objects are managed by
devres, hence they'll be released automagically.

0899a7a230 ALSA: pci: rme: Set up buffer type properly
Although the regression of the mmap was fixed in the recent commit
dc0dc8a73e ("ALSA: pcm: Fix mmap breakage without explicit buffer
setup"), RME9652 and HDSP drivers have still potential issues with
their mmap handling.  Namely, they use the default mmap handler
without the standard buffer preallocation, and PCM core wouldn't use
the coherent DMA mapping.  It's practically OK on x86, but on some
exotic architectures, it wouldn't work.

This patch addresses the potential breakage by replacing the buffer
setup with the proper macro.  It also simplifies the source code,
too.

5b1ed7df01 ALSA: control - add generic LED API
This patchset tries to resolve the diversity in the audio LED
 control among the ALSA drivers. A new control layer registration
 is introduced which allows to run additional operations on
 top of the elementary ALSA sound controls.
 
 A new control access group (three bits in the access flags)
 was introduced to carry the LED group information for
 the sound controls. The low-level sound drivers can just
 mark those controls using this access group. This information
 is not exported to the user space, but user space can
 manage the LED sound control associations through sysfs
 (last patch) per Mark's request. It makes things fully
 configurable in the kernel and user space (UCM).
 
 The actual state ('route') evaluation is really easy
 (the minimal value check for all channels / controls / cards).
 If there's more complicated logic for a given hardware,
 the card driver may eventually export a new read-only
 sound control for the LED group and do the logic itself.
 
 The new LED trigger control code is completely separated
 and possibly optional (there's no symbol dependency).
 The full code separation allows eventually to move this
 LED trigger control to the user space in future.
 Actually it replaces the already present functionality
 in the kernel space (HDA drivers) and allows a quick adoption
 for the recent hardware (ASoC codecs including SoundWire).
 
 snd_ctl_led            24576  0
 
 The sound driver implementation is really easy:
 
 1) call snd_ctl_led_request() when control LED layer should be
    automatically activated
    / it calls module_request("snd-ctl-led") on demand /
 2) mark all related kcontrols with
         SNDRV_CTL_ELEM_ACCESS_SPK_LED or

da2a040ee7 ALSA: hdsp: hardware output loopback
Output loopback is a feature where you can record what you hear.
The HDSP series of the RME interfaces provides this functionality
at the hardware level and this patch exposes controls to enable or
disable it per output (playback) channel.

This probably works on other cards but due to a lack of hardware
it is only tested and enabled for the HDSP9632 card with this patch.

Should this patch be accepted a separate patch will be posted to
https://github.com/alsa-project/alsa-tools/tree/master/hdspmixer
which adds "LPBK" buttons to each output in the playback strip for
the user to be able to control this feature from the user land.
Users from Windows tool TotalMixFX should be familiar with this.

75b1a8f9d6 ALSA: Convert strlcpy to strscpy when return value is unused
strlcpy is deprecated.  see: Documentation/process/deprecated.rst

Change the calls that do not use the strlcpy return value to the
preferred strscpy.

Done with cocci script:

@@
expression e1, e2, e3;
@@

-	strlcpy(
+	strscpy(
	e1, e2, e3);

This cocci script leaves the instances where the return value is
used unchanged.

After this patch, sound/ has 3 uses of strlcpy() that need to be
manually inspected for conversion and changed one day.

$ git grep -w strlcpy sound/
sound/usb/card.c:               len = strlcpy(card->longname, s, sizeof(card->longname));
sound/usb/mixer.c:      return strlcpy(buf, p->name, buflen);
sound/usb/mixer.c:                      return strlcpy(buf, p->names[index], buflen);

Miscellenea:

a2e527c5a3 ALSA: hdspm: Replace tasklet with work
The tasklet is an old API that should be deprecated, usually can be
converted to another decent API.  In HDSP-MADI driver, a tasklet is
still used for offloading the MIDI I/O handling (optional via mixer
switch).  It can be achieved gracefully with a work queued, too.

This patch replaces the tasklet usage in HDSP-MADI driver with a
simple work.  The conversion is fairly straightforward.  The only
significant difference is that the work initialization is moved to the
right place in snd_hdspm_create() and cancel_work_sync() is always
called in snd_hdspm_free() to assure killing the pending works.

112e3f5ac5 ALSA: hdsp: Make the firmware loading ioctl a bit more readable
The firmware loading ioctl that is implemented for hdsp hwdep device
takes the reference of the address pointer, hence the current code is
rather confusing.  Also, due to the recent change in uapi header,
sparse also complains about the cast.

This patch tries to improve the readability by converting the
straightforward copy_from_user of the whole struct (which contains
only the pointer).

fb95aae6e6 sound updates for 5.6-rc1
As diffstat shows we've had again a lot of works done for this cycle:
 majority of changes are the continued componentization and code
 refactoring in ASoC, the tree-wide PCM API updates and cleanups
 and SOF updates while a few ASoC driver updates are seen, too.
 
 Here we go, some highlights:
 
 Core:
 - Finally y2038 support landed to ALSA ABI;
   some ioctls have been extended and lots of tricks were applied
 - Applying the new managed PCM buffer API to all drivers;
   the API itself was already merged in 5.5
 - The already deprecated dimension support in ALSA control API is
   dropped completely now
 - Verification of ALSA control elements to catch API misuses
 
 ASoC:
 - Further code refactorings and moving things to the component level
 - Lots of updates and improvements on SOF / Intel drivers;
   now including common HDMI driver and SoundWire support
 - New driver support for Ingenic JZ4770, Mediatek MT6660, Qualcomm
   WCD934x and WSA881x, and Realtek RT700, RT711, RT715, RT1011, RT1015
   and RT1308
 
 HD-audio:
 - Improved ring-buffer communications using waitqueue
 - Drop the superfluous buffer preallocation on x86
 
 Others:
 - Many code cleanups, mostly constifications over the whole tree
 - USB-audio: quirks for MOTU, Corsair Virtuoso, Line6 Helix
 - FireWire: code refactoring for oxfw and dice drivers

d63e63d421 ALSA: hdsp: Make uapi/hdsp.h compilable again
Recently alsa-lib updated its content of sound/hdsp.h just by copying
the latest Linus kernel uapi/*.h, and this broke the build of
alsa-tools programs.  We used to modify the headers so that they can
be built without asoundlib.h and linux kernel headers, and the
verbatim copy doesn't work as is.

This patch removes again the linux/types.h inclusion and drop __user
prefix that broke the build and adjusts the corresponding code.

39cccf4511 ALSA: rme9652: Support PCM sync_stop
The driver invokes snd_pcm_period_elapsed() simply from the interrupt
handler.  Set card->sync_irq for enabling the missing sync_stop PCM
operation.

1a810436a2 ALSA: rme: Avoid non-standard macro usage
Pass the device pointer from the PCI pointer directly, instead of a
non-standard macro.  The macro didn't give any better readability.

Along with it, drop the unnecessary assignment before the
snd_dma_alloc_pages() call and simplify by returning the error code
directly.
