Lars-Peter Clausen fabfad2f8b ASoC: wm8958: Move DSP firmware lock to driver level
The wm8958 driver uses the snd_soc_codec mutex to protect the various
firmware pointers from concurrent assignment. This patch moves this lock to
the driver level. This will allow us to eventually remove the snd_soc_codec
mutex.
