From: Shenghao Ding
Date: Mon Sep 04 2023 - 10:02:32 EST


Revert structure name back to cs35l41_dev_name and redefine
tas2781_generic_fixup.

Signed-off-by: Shenghao Ding <shenghao-ding@xxxxxx>

Changes in v2:
- Add more description on why revert structure name back to
cs35l41_dev_name
- Redefine tas2781_generic_fixup, remove hid argument, and do not use
structure scodec_dev_name any more in tas2781_generic_fixup.
- remove cs35l41_dev_name from comp_match_tas2781_dev_name, which is
useless. bus name is passed by tas2781_generic_fixup, hid is actually
"TIAS2781", can be hardcode and unneeded argument passed from
tas2781_generic_fixup.
Index is a redundant member, and never used in tas2781 hda driver.
- revert from scodec_dev_name back to cs35l41_dev_name, tas2781 pass only
bus name instead of cs35l41_dev_name, so it seemed unnecessary for
tas2781.
