[alsa-devel] [PATCH 1/4] ASoC: wm_adsp: Correct cache handling of new kernel control API
by Charles Keepax 17 Jan '20

17 Jan '20

The recently added API that exposes firmware mixer controls to the kernel is missing cache handling and all writes bypass the cache, this obviously causes the cache to get out of sync with the hardware. Factor out the cache handling into two new helper functions and call those from both the normal ALSA control handlers and the new kernel API.
