[PATCH v3 3/3] ALSA: hda/tas2781: Firmware load for tas2781 driver for SPI

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Firmware download and parser lib for tas2781, it work for spi
device with a single firmware binary file.

Signed-off-by: Baojun Xu <baojun.xu@xxxxxx>

---
v3:
 - Update format and variables declare order.
 - Change format of multi conditions for if.
 - Remove casting which is not needed.
 - Change variables type to avoid casting.
 - Remove Unneeded parentheses.
 - Change if check to avoid goto.
 - Add {} for keep same style.
 - Remove some local variables, use elements in structure directly.
