The device indicates the result of a read/write operation by making the
status available on a subsequent request from the driver. This is not
ready immediately, though, so the driver is currently slamming the
device with hundreds of pointless requests before getting the expected
response. Add a two millisecond delay before each attempt. This is
approximately the behavior observed with version 4.2.7.1 of the Windows
driver.

The BDW audio firmware DSP manages the DMA and the DMA cannot be
stopped exactly at the end of the playback stream. This means
stale samples may be played at PCM stop unless the driver copies
silence to the subsequent periods.

The first URBs are submitted during the prepare stage. When .trigger is
called, the ALSA core saves a trigger tstamp that doesn't correspond to
the actual time when the samples are submitted. The trigger_tstamp is
now updated when the first data are submitted to avoid any time offsets.
A usb-specific trigger_tstamp_pending_update flag is used for now,
at some point the flag would need to move to the ALSA core, USB
is not the only interface where silent block transfers are programmed
as part of the prepare stage, with actual data enabled when .trigger
is called.

The problem here is that we check:
if (dev >= SNDRV_CARDS)
Then we increment "dev".
if (!joystick_port[dev++])
Then we use it as an offset into a array with SNDRV_CARDS elements.
if (!request_region(joystick_port[dev], 8, "Riptide gameport")) {
This has 3 effects:
1) If you use the module option to specify the joystick port then it has
to be shifted one space over.
2) The wrong error message will be printed on failure if you have over
32 cards.
3) Static checkers will correctly complain that are off by one.

Function sst_acpi_probe() uses plain strcpy for setting member firmware_name
of a struct intel_sst_drv from member firmware of a struct sst_machines.
Thereby the destination array has got a length of 20 byte while the source may
hold 32 byte. Since eg. commit 64b9c90b86 ("ASoC: Intel: Fix BYTCR firmware
name") increased strings from "fw_sst_0f28.bin" to "intel/fw_sst_0f28.bin"
there is an actual possibility that the 20 byte array at the end of struct
intel_sst_drv is overrun.
Thus increase the size of the destination and use the same define for both
structs. Detected by Coverity CID 1260087.

For assigning sysfs entries for a card device from the driver,
introduce a new helper function, snd_card_add_dev_attr(). In this
way, we can avoid the possible race between the device registration
and the sysfs addition / removal.
The driver can pass a new attribute group to add freely. This has to
be called before snd_card_register().
Currently, up to two extra groups can be added. More than that, it'll
return an error.
