Pull drm fixes from Dave Airlie:
"Nothing too major or scary.
One i915 regression fix, nouveau has a tmds regression fix, along with
a regression fix for the runtime pm code for optimus laptops not
restoring the display hw correctly"
* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
drm/nouveau: make sure display hardware is reinitialised on runtime resume
drm/nouveau: punt fbcon resume out to a workqueue
drm/nouveau: fix regression on original nv50 board
drm/nv50/disp: fix dpms regression on certain boards
drm/i915: Flush the PTEs after updating them before suspend
Drivers should not call pm_power_off directly; it is not guaranteed
to be non-NULL. Call kernel_power_off instead.

Module signing matches keys by comparing against the key description exactly.
However, the way the key description gets constructed got changed to be
composed of the subject name plus the certificate serial number instead of the
subject name and the subjectKeyId. I changed this to avoid problems with
certificates that don't *have* a subjectKeyId.
Instead, if available, use the raw subjectKeyId to form the key description
and only use the serial number if the subjectKeyId doesn't exist.

Current caching implementation during regcache_sync() call bypasses
all register writes of values that are already known as default
(regmap reg_defaults). Same time in TLV320AIC3x codecs register 5
(AIC3X_PLL_PROGC_REG) write should be immediately followed by register
6 write (AIC3X_PLL_PROGD_REG) even if it was not changed. Otherwise
both registers will not be written.
This brings to issue that appears particulary in case of 44.1kHz
playback with 19.2MHz master clock. In this case AIC3X_PLL_PROGC_REG
is 0x6e while AIC3X_PLL_PROGD_REG is 0x0 (same as register
default). Thus AIC3X_PLL_PROGC_REG also remains not written and we get
wrong playback speed.
In this patch snd_soc_read() is used to get cached pll values and
snd_soc_write() (unlike regcache_sync() this function doesn't bypasses
hardware default values) to write them to registers.

Commit 0bd2ac3dae ("ASoC: Remove CODEC pointer from snd_soc_dapm_context")
introduced regression to snd_soc_dapm_new_controls() when registering a card
with card->dapm_widgets set. Call chain is:
snd_soc_register_card()
-> snd_soc_instantiate_card()
-> snd_soc_dapm_new_controls()
-> snd_soc_dapm_new_control()
Null pointer dereference occurs since card->dapm context doesn't have
associated component. Fix this by setting widget codec pointer
conditionally.

Unlike the clocks management code for runtime PM, the code used for
system suspend does not check the pm_clock_entry.status field.
If pm_clk_acquire() failed, ce->status will be PCE_STATUS_ERROR, and
ce->clk will be a negative error code (e.g. 0xfffffffe = -2 = -ENOENT).
Depending on the clock implementation, suspend or resume may crash with:
Unable to handle kernel NULL pointer dereference at virtual address 00000026
(CCF clk_disable() has an IS_ERR_OR_NULL() check, while CCF clk_enable()
only has a NULL check; pre-CCF implementations may behave differently)
While just checking for PCE_STATUS_ERROR would be sufficient, it doesn't
hurt to use the same state machine as is done for runtime PM, as this
makes the two versions more similar, and eligible for a future
consolidation.

The "cpu_data" are defined for some archs and thus conflicting with the
"cpu_data" member in the struct gpd_cpu_data. This causes a compiler
error for those archs.
Let's fix it by rename the member to cpuidle_data. In this context it
also seems appropriate to rename the struct to gpd_cpuidle_data to
better reflect its use.

If cpufreq_generic_init() fails we jump into the resource
cleanup path which contains a of_node_put() call. Another
instance of this has already been called at that time
resulting a double decrement of the refcount.
Fix this by calling of_node_put() only after we are sure
that nothing has gone wrong.

The naming convention of this driver was always under the scanner, people
complained that it should have a more generic name than cpu0, as it manages all
CPUs that are sharing clock lines.
Also, in future it will be modified to support any number of clusters with
separate clock/voltage lines.
Lets rename it to 'cpufreq_dt' from 'cpufreq_cpu0'.
