615cb24326 drm/i915: Drop the broken cursor base==0 special casing
The cursor code tries to treat base==0 to mean disabled. That fails
when the cursor bo gets bound at ggtt offset 0, and the user is left
looking at an invisible cursor.

We lose the disabled->disabled optimization, but that seems like
something better handled at a slightly higher level.

9ae482104c gpio: 104-idi-48: Clear pending interrupt once in IRQ handler
Performing a read operation on the IRQ Status register will clear the
IRQ latch. Since a read operation on the IRQ Status register must be
performed in the IRQ handler in order to determine if the IRQ was in
fact generated by the device, the IRQ latch is consequently cleared by
the IRQ handler. A spinlock is used to guarantee that each IRQ is
serviced in the order it was received.

9f660a1c43 ALSA: hda/realtek - Fix silent headphone output on MacPro 4,1 (v2)
Without this patch, internal speaker and line-out work,
but front headphone output jack stays silent on the
Mac Pro 4,1.

This code path also gets executed on the MacPro 5,1 due
to identical codec SSID, but i don't know if it has any
positive or adverse effects there or not.

(v2) Implement feedback from Takashi Iwai: Reuse
     alc889_fixup_mbp_vref and just add a new nid

If you like my patch for that, I'd be happy to see it applied directly.

This pull request brings in little fixes from Dan Carpenter for the 3D

9c1d9c207b sd: Reject optimal transfer length smaller than page size
Eryu Guan reported that loading scsi_debug would fail. This turned out
to be caused by scsi_debug reporting an optimal I/O size of 32KB which
is smaller than the 64KB page size on the PowerPC system in question.

Add a check to ensure that we only use the device-reported OPTIMAL
TRANSFER LENGTH if it is bigger than or equal to the page cache size.

e7cfb3907d staging/emxx_udc: fix 64-bit warnings
ARCH_SHMOBILE is coming to arm64, which creates new warnings in allmodconfig:

drivers/staging/emxx_udc/emxx_udc.c: In function '_nbu2ss_out_dma':
drivers/staging/emxx_udc/emxx_udc.c:843:45: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
  _nbu2ss_writel(&preg->EP_DCR[num].EP_TADR, (u32)pBuffer);

This is clearly a mistake from confusing a dma_addr_t with a pointer,
so the fix is to use the correct types in two places.

The third warning of this kind is a check for an unaligned pointer,
which should be done by casting the pointer to uintptr_t, not int.

479bd5edab staging: comedi: s526: replace counter mode bitfield struct
The driver uses `struct counter_mode_register_t` to describe the 16-bit
counter mode register as a sequence of bitfield members.  The struct
appears as the type of one of the members of `union cmReg`, the other
member of which is of type `unsigned short`, so the driver can
manipulate the register value as a whole, or as individual fields.
Although this is fairly convenient, it's not that conventional.  The
code also needs to define the bitfield members in ascending or
descending order of the physical bits, depending on whether bitfields
are little- or big-endian.

Rip all that out and replace it with a bunch of macros to set and mask
out bits of the register value, as that's the more conventional way to
do it.  A bonus is that we get rid of a load of CamelCase definitions in
the process.

28a60c456b staging: comedi: check for more errors for zero-length write
If the "write" file operation handler, `comedi_write()` is passed 0 for
the amount to write, some error conditions are currently skipped and the
function just returns 0.  Change it to check those error conditions and
return an error value if appropriate.  The trickiest case is the check
for when the previously set up asynchronous command has terminated with
an error.  In that case, `-EPIPE` is returned (as it is for a write of
non-zero length) and the subdevice gets marked as non-busy.

A zero-length write that returns 0 has no other effects, in particular,
it does not cause the subdevice to be marked as non-busy.

3318c7add8 staging: comedi: simplify returned errors for comedi_write()
In order to perform a "write" file operation, an asynchronous COMEDI
command in the "write" direction needs to have been set up by the
current file object on the COMEDI "write" subdevice associated with the
file object.  If there is a "write" subdevice, but a command has not
been set up by the file object (or is has been set-up in the wrong
direction), `comedi_write()` currently returns one of two error values
`-EINVAL` or `-EACCES`.  `-EACCES` is returned if the command was set up
by a different subdevice, or somewhat randomly, if a COMEDI
"instruction" is currently being processed.  `-EINVAL` is returned in
other cases.  Simplify it by returning `-EINVAL` for all these cases.

40d0e80e08 staging: comedi: return error on "write" if no command set up
The "write" file operation handler, `comedi_write()` returns an error
for pretty much any condition that prevents a "write" going ahead.  One
of the conditions that prevents a "write" going ahead is that no
asynchronous command has been set up, but that currently results in a
return value of 0 (unless COMEDI instructions are being processed or an
asynchronous command has been set up by a different file object).
Change it to return `-EINVAL` in this case.
