[PATCH v2 00/28] Clean-up ASoC's W=1 build warnings
This set is part of a larger effort attempting to clean-up W=1 kernel builds, which are currently overwhelmingly riddled with niggly little warnings.
After these patches are applied, the build system no longer complains about any W=0 nor W=1 level warnings in sound/soc, when building for Arm.
Hurrah!
Changelog
v1 => v2: - Remove whole read from patch 21 - Suggested by Peter
