[alsa-devel] Is the mixer interface in the kernel protect against concurrent access?

[Hans-Christian Egtvedt]

Hi,

I am solving a locking bug in the at73c213 SPI sound driver, and
wondered if the mixer API is protected against concurrent access in
ALSA? Or should I implement a mutex to protect my hardware against
concurrent access?
