[SCSI] libsas: fix build dependencies on libata

The problem is that if you compile in libsas, you can't build libata

Add the Osprey 440 to the Bt878 ALSA driver's whitelist. Currently the sample
rate is fixed at 32kHz, as the driver doesn't support different rates for
digital input mode, though the card can select the rate from 32, 44.1, or 48
kHz via gpio.
Setting the audio gain via ALSA isn't supported yet; a userspace tool that

would think this frame was currently being captured, and wait for it to
complete before starting a new frame. The hardware on the other hand would
not be actively capturing a frame. The result was the driver would wait
forever for v4l_grab_frame to be captured.

During uncompressed capture, the poll() function was looking the wrong frame.
It was using the frame the driver was going to capture into next (pend_tail),
when it should have been looking at the next frame to be de-queued with
DQBUF/SYNC (sync_tail).
It also wasn't looking in the right spot. It was looking at the file handle's
copy of the buffer status, rather than the driver core copy. The interrupt
routine marks frames as done in the driver core copy, the file handle copy
isn't updated. So even if poll() looked at the right frame, it would never
see it transition to done and return POLLIN.
The compressed capture code has this same problem, looking in fh->jpg_buffers
when it should have used zr->jpg_buffers.
There was some logic to detect when there was no current capture in process
nor any frames queued and try to return an error, which ends up being a bad
idea. It's possible to call select() from one thread while no capture is in
process, or no frames queued, and then start a capture or queue frames from
another thread.
The buffer state variables are protected by a spin lock, which the code wasn't
acquiring. That is fixed too.

V4L/DVB (5886): zr36067: Fix problem setting norms
The zr36067 driver doesn't make a distinction between the different sub-types
of NTSC, PAL, or SECAM norms. For example, when the enum std ioctl returns
the PAL standard it returns PAL_BG|PAL_DK|PAL_H|PAL_I.
When setting the norm, it required the bitmask to match exactly the set of
norms used during the enumeration. If just one norm was specified, for
example PAL_BG or NTSC_M, it would fail. This violates the V4L2 spec,
"VIDIOC_S_STD accepts *one* or more flags..."
The key thing to realize is that V4L2_STD_PAL is not one bit, it is multiple
bits. It's ok to call S_STD with any *one* of those bits, but the driver was
requiring *all* of them.
This fixes the S_STD function so that it will accept any set of one or more
PAL norms as PAL, and the same for NTSC and SECAM.

[SPARC]: Mark SBUS framebuffer ioctls as IGNORE in compat_ioctl.c
They are handled in a ->compat_ioctl() handler, so it's just noise
when compat_ioctl.c warns which occurs when they are used on non-SBUS
framebuffer devices.

[SPARC64]: Fix conflicts in SBUS/PCI/EBUS/ISA DMA handling.
Fully unify all of the DMA ops so that subordinate bus types to
the DMA operation providers (such as ebus, isa, of_device) can
work transparently.
Basically, we just make sure that for every system device we
create, the dev->archdata 'iommu' and 'stc' fields are filled
in.
Then we have two platform variants of the DMA ops, one for SUN4U which
actually programs the real hardware, and one for SUN4V which makes
hypervisor calls.
This also fixes the crashes in parport_pc on sparc64, reported by
Meelis Roos.

etc. etc. code sequence, basically replicating the provided
framebuffer_alloc()/framebuffer_release(), and doing it badly.
Not only is this massive code duplication, it also caused a
bug in that we weren't setting the fb_info->device pointer
which results in an OOPS when fb_is_primary_device() runs.
Fix all of this by using framebuffer_{alloc,release}() and
passing in "&of_device->dev" as the device pointer.
