[alsa-devel] [PATCH] ASoC: simple-card: Add mic and hp detect gpios.
by Dylan Reid 22 Oct '14

22 Oct '14

Allow Headphone and Microphone jack detect gpios to be specified in device tree. This will allow a few systems including rk3288_max98090 to use simple-card instead of having their own board file.

[alsa-devel] [PATCH] ASoC: rt5677: fix rt5677 spi driver build
by Ben Zhang 21 Oct '14

21 Oct '14

Create a separate module for rt5677 spi driver. Without this patch, the build fails due to multiple defs of 'init_module' and 'cleanup_module'. module_spi_driver() defines its own module, so it can't be part of the rt5677 module.

As of now the pointer to struct dai is not being used anywhere in the function. So it is safe to remove the variable. If we are ever doing anything with the container_of(daio, struct dai, daio), then at that time we can again add the variable.
