[PATCH v1 0/4] ALSA: hda/cirrus: Make CS8409 driver more generic by using fixups

[Vitaly Rodionov]

This series of patches will address comments by Pierre-Louis Bossart,
cleans up patch_cirrus.c source, reducing checkpatch.pl warnings from 19 to 0,
fixing an issue reported by Canonical: BugLink: https://bugs.launchpad.net/bugs/1918378,
and makes the CS8409 patch more generic by using fixups.

Stefan Binding (4):
  ALSA: hda/cirrus: Add error handling into CS8409 I2C functions
  ALSA: hda/cirrus: Cleanup patch_cirrus.c code.
  ALSA: hda/cirrus: Fix CS42L42 Headset Mic volume control name
  ALSA: hda/cirrus: Make CS8409 driver more generic by using fixups.

[PATCH v1 3/4] ALSA: hda/cirrus: Fix CS42L42 Headset Mic volume control name

[Vitaly Rodionov]

From: Stefan Binding <sbinding@opensource.cirrus.com>

Existing name "Headset Mic Volume Control" causes multiple Microphone
entries to appear in UI. Using name "Mic Volume Control" ensures only a
single Microphone entry exists when the Headset is connected.

[PATCH v1 4/4] ALSA: hda/cirrus: Make CS8409 driver more generic by using fixups.

[Vitaly Rodionov]

From: Stefan Binding <sbinding@opensource.cirrus.com>

CS8409/CS42L42 Driver currently does most of the platform specific
setup inside the main body of the code, however, this setup can be
moved into fixup functions, to make the driver more generic.

Making the driver more generic, allows the driver to use the
cs_parse_auto_config function in the patch function. This function
forces all of the ADCs to be permanently powered, which means the
cap_sync_hook function is no longer needed to restart the stream, when
the jack has been ejected.

Since the codec is re-initialized on every init/resume, there is no
need to add specific verbs to be run on init, and instead these can
be combined with the initialization verbs, which are run on init.

In addition, the extra fixup verbs are no longer required, since this
is taken care of elsewhere.

Tested on DELL Inspiron-3505, DELL Inspiron-3501, DELL Inspiron-3500

Hi Takashi,

Yes, this is second version of same series, where we have fixed warnings 
from 0-day bot.

If the return value of the function has changed, it's nicer to
comment, e.g. a brief function description would be helpful.
Also now this looks rather like a bool?

Why those two calls are removed?

Parentheses around the comparison are superfluous, you can remove
them.

Those widgets are all pin widgets, right?  If so, setting via the
pincfg table would be more suitable, as it's cached and exposed via
sysfs for debugging.

This 2 call are redundant as we already did read these 2 registers in a

Yes, you are right, actually we already have these widgets in pincfg 
table, so this code is redundant.
