[alsa-devel] [PATCH 2/7] ASoC: kirkwood-i2s: provide helper KIRKWOOD_RECCTL_ENABLE_MASK definition

Russell King rmk+kernel at arm.linux.org.uk
Thu Jun 26 16:22:55 CEST 2014


Add a KIRKWOOD_RECCTL_ENABLE_MASK definition to complement the existing
PLAYCTL definition, and make use of it where we wish to clear both
enable bits.
