4ef61076f8 sound fixes for 3.16-rc2
The significant part here is a few security fixes for ALSA core
 control API by Lars.  Besides that, there are a few fixes for ASoC
 sigmadsp (again by Lars) for building properly, and small fixes for
 ASoC rsnd, MMP, PXA and FSL, in addition to a fix for bogus WARNING in
 i915/HD-audio binding.

fb54918af7 drm: fix uninitialized acquire_ctx fields (v2)
The acquire ctx will typically be declared on the stack, which means we
could have garbage values for any uninitialized field.  In this case, it
was triggering WARN_ON()s because 'contended' had garbage value.

Go ahead and use memset() to be more future-proof.

v2: now with extra brown paper bag

74b0c2d75f drm/i915, HD-audio: Don't continue probing when nomodeset is given
When a machine is booted with nomodeset option, i915 driver skips the
whole initialization.  Meanwhile, HD-audio tries to bind wth i915 just
by request_symbol() without knowing that the initialization was
skipped, and eventually it hits WARN_ON() in i915_request_power_well()
and i915_release_power_well() wrongly but still continues probing,
even though it doesn't work at all.

In this patch, both functions are changed to return an error in case
of uninitialized state instead of WARN_ON(), so that HD-audio driver
can give up HDMI controller initialization at the right time.

4366f3b5f5 drm/radeon: Bypass hw lut's for > 8 bpc framebuffer scanout.
The hardware lut's only have 256 slots for indexing by a
8 bpc framebuffer. In 10 bpc scanout modes, framebuffer
color values would get truncated to their 8 msb's,
thereby losing the extra precision afforded by a 10 bpc
framebuffer.

To retain full precision, bypass the hw lut in 10 bpc
scanout mode.

2b85886a54 drm/i915: Avoid div-by-zero when pixel_multiplier is zero
On certain platforms pixel_multiplier is read out in
.get_pipe_config(), but it also gets used to calculate the
pixel clock in intel_sdvo_get_config(). If the pipe is disable
but some SDVO outputs are active, we may end up dividing by zero
in intel_sdvo_get_config().

To avoid the problem simply check for zero pixel_multiplier and skip
the division. Another attempt at fixing this involved populating
pixel_multiplier to 1 even for disabled pipes, but that triggered a
WARN because SDVO_CMD_GET_CLOCK_RATE_MULT command failed and thus
encoder_pixel_multiplier was left at zero and didn't match
pipe_config->pixel_multiplier.

The "divide by pixel_multiplier" operation got introduced here:

0368920e51 drm/i915: Disable FBC by default also on Haswell and later
It causes black screen on bootup and is approximately 100x slower than
running with FBC disabled, so the GPU runs at a high frequency for much
longer - completely contrary to the power saving claims. It also still
has mutex deadlocks in multi-head scenarios, which can lead to a
system/X lockup. These bugs were known before FBC was enabled by default
on Haswell and still have not been fixed.

efa366fdf5 drm/nv50-: trigger update after all connectors disabled
We were sending the necessary state changes to unset the mode, but
never actually hit the big GO button unless another modeset happens
afterwards.

4874322e78 drm/nouveau/dp: fix support for dpms
SOR_PWR has no effect to power-off DP links, unlike other SOR protocols.

Instead, on the source side, we cut power to the lanes after having put
the sink into D3.  Link training takes care of everything required to
bring it back again.

55f083c33f drm/nouveau/disp/dp: maintain link in response to hpd signal
This previously worked for the most part due to userspace doing a
modeset in response to HPD interrupts.  This will allow us to
properly handle cases where sync is lost for other reasons, or if
userspace isn't caring.
