[alsa-devel] Function ap192_4wire_start in revo.c

Hello, while working on support for AK4114 in Audiotrak MI/ODI/O, I have come accross a bug in revo.c (used for major inspiration :) )The function

static unsigned char ap192_4wire_start(struct snd_ice1712 *ice)

returns value of current GPIO bits, which is unsigned int. However, return value of the function is unsigned char. This results in clearing all GPIO8-22 in next snd_ice1712_gpio_write call of the 4-wire protocol communication which is a little bit inconvenient :).

Thanks for fixing in HG.

Best regards,

Pavel.
