1adecc6755 ALSA: hda - Add some FIXUP quirks for white noise on Dell laptop.
Dell laptop has a series model to use the same codec but different subsystem ID.
At the same time they happens the white noise by login screen and headphone;
for fixing them together, I only can add these IDs to FIXUP function ALC292_FIXUP_DISABLE_AAMIX,
then try to solve such the similar issues.

9f502ff553 ALSA: hda - yet another fix for Dell headset mic with ALC3266
It turned out that there are three variants of pin config values of
NID 0x17 on Dell laptops with ALC3266 (alias of ALC298): 0x90170110,
0x90170140 and 0x90170150.  The first two have been already covered by
commits 703867e2f2 and 977e627684, so this commit adds the missing
last entry.

While we're at it, rearrange the three entries in the order of pincfg
values.

703867e2f2 ALSA: hda - Fix Dell laptop for internal mic/headset mic
The new Dell laptop with ALC3266 can't use internal microphone to
record. Also, the 3 ring headset mic doesn't work on it. For src of
patch_realtek.c, only the pin cfg of Nid 0x17 is different, so the
Nid 0x17 is added into pin quirk, and others are defined to macro
ALC298_STANDARD_PINS in common use.

To cleanup the pin_quirk table:
 - rewrite the pin_config_match(), comparing all pins on the machine
   with the corresponding pins in the quirk table.
 - remove all 0x4xxxxxxx pin configurations from pin_quirk table
 - after removing the 0x4xxxxxxx pin configurations, some pin tables
   are exactly same, so removing the redudant pin tables.

5ce000b297 ALSA: hda - Add pin quirk for the headset mic jack detection on Dell laptop
The new Dell laptop with codec 256 can't detect headset mic when
headset was inserted on the machine. From alsa-info, we check
init_pin_configs and need to define the new register value for pin
0x1d & 0x1e because the original macro ALC256_STANDARD_PINS can't
match pin definition. Also, the macro ALC256_STANDARD_PINS is
simplified by removing them. This makes headset mic works on laptop.

This laptop needs GPIO4 pulled high to enable the headphone amplifier,

the HP amp line is pulled high.

v2: Disable the headphone amplifier when no headphone is connected.
    Don't disable power savings to preserve the LED state.

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.

8b99aba70c ALSA: hda - Fix audio crackles on Dell Latitude E7x40
We still got a report that the audio crackles and noises occur with
the recent 4.1 kernels on Dell machines.  These machines seem to need
similar workarounds that have been applied to the recent Dell XPS 13
models.  Since the codec of these machines (Dell Latitute E7240 and
E7440) is different from XPS 13's one, we need a new fixup entry.

Also, it was confirmed that the previous workaround to disable the
widget power-save (commit [219f47e4f9: ALSA: hda - Disable widget
power-saving for ALC292 & co]) is no longer needed after this fix.
So, this patch includes the partial revert of the commit, too.

7d1b6e2932 ALSA: hda - fix "num_steps = 0" error on ALC256
The ALC256 does not have a mixer nid at 0x0b, and there's no
loopback path (the output pins are directly connected to the DACs).

This commit fixes an "num_steps = 0 for NID=0xb (ctl = Beep Playback Volume)"
error (and as a result, problems with amixer/alsamixer).

If there's pcbeep functionality, it certainly isn't controlled by setting an
amp on 0x0b, so disable beep functionality (at least for now).

9476d369d7 ALSA: hda - Mute headphone pin on suspend on XPS13 9333
Muting the headphone output pin right before the codec suspension
prevents pop noises when headphones are plugged in (except for a
barely audible click noise).
This solution allows to truly save some power when headphones are
plugged in unlike the previous solution (033b0a7ca9:
"ALSA: hda - Pop noises fix for XPS13 9333")
