The snd_info_free_entry() function tests whether its argument is NULL and
then returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.

Dell E7450 [0128:062e] needs the same quirk as other E7xx models.

Fujitsu Lifebook E780 sets the sequence number 0x0f to only only of
the two headphones, thus the driver tries to assign another as the
line-out, and this results in the inconsistent mapping between the
created jack ctl and the actual I/O.  Due to this, PulseAudio doesn't
handle it properly and gets the silent output.

The fix is to ignore the non-HP sequencer checks.

Acer Aspire V5 with ALC282 codec needs the similar quirk like Dell
laptops to support the headset mic.  The headset mic pin is 0x19 and
it's not exposed by BIOS, thus we need to fix the pincfg as well.

Those FIXUPs were applied to the machines through pin quirks, but

While the commit [d0a601c2: ALSA: jack: Fix the id uniqueness
check] fixes the wrong string check, it leads to a worse result -- the
loop in get_available_index() goes into an endless loop.  The cause is
that snd_ctl_find_id() returns the object assigned to the numid if
it's set.  Thus it points to the previous entry again.

This patch clears the numid field for the next call properly.

The widget power-save that was enabled in 4.1 kernel seems resulting
in the silent output on VIA codecs by some reason.  Some widgets get
wrong power states.

As a quick fix, turn this flag off while keeping power_down_unused
flag.  This will bring back to the state of 4.0.x.

Thinkpad X250, when attached to a dock, has two headphone outs but
no line out. Make sure we don't try to turn this into one headphone
and one line out (since that disables the headphone amp on the dock).

ASoC: Further updates for v4.2

There's a bunch of additional updates and fixes that came in since my
orignal pull request here, including DT support for rt5645 and fairly
large serieses of cleanups and improvements to tas2552 and rcar.

ASoC: Updates for v4.2

The big thing this release has been Liam's addition of topology support
to the core.  We've also seen quite a bit of driver work and the
continuation of Lars' refactoring for component support.

 - Support for loading ASoC topology maps from firmware, intended to be
   used to allow self-describing DSP firmware images to be built which
   can map controls added by the DSP to userspace without the kernel
   needing to know about individual DSP firmwares.
 - Lots of refactoring to avoid direct access to snd_soc_codec where
   it's not needed supporting future refactoring.
 - Big refactoring and cleanup serieses for the Wolfson ADSP and TI
   TAS2552 drivers.
 - Support for TI TAS571x power amplifiers.
 - Support for Qualcomm APQ8016 and ZTE ZX296702 SoCs.
 - Support for x86 systems with RT5650 and Qualcomm Storm.

The rate controls are codec-specific, it's not possible to
generically say what the range or the meaning of each control
is (or even if they exist at all) - that depends on the
particular codec.

This is currently being handled for Arizona codecs by putting
an Arizona-specific table of controls inside the wm_adsp driver.
This creates a dependency between wm_adsp and arizona.c, and is an
awkward solution if the ADSP is used in another family of codecs

Fix this by moving the Arizona-specific rate controls into the
Arizona codec drivers.
