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.

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

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.

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

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

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.

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

Will fix in next version.

Hi Takashi,

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

Thanks,
