Subject: [PATCH v3 1/3] ALSA: hda/tas2781: Modification for add tas2781 driver for SPI
Date: Thu, 18 Apr 2024 12:02:37 +0800

Integrate tas2781 configs for HP Laptops. Every tas2781 in the laptop
will work as a single speaker on SPI bus. The code support realtek as
the primary codec.

v3:
 - Move HID up to above /* Non-conforming _HID ... */ in scan.c,
   for avoid misunderstanding.
 - Move HID up to above /* Non-conforming _HID ... */ in
   serial-multi-instantiate.c, for avoid misunderstanding.
 - Change objs to y for snd-hda-scodec-tas2781-spi- in Makefile.
