[PATCH 3/4] drm/omap: Remove set but not used variable 'err' in hdmi5_audio_config

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/omapdrm/dss/hdmi5_core.c: In function hdmi5_audio_config:
drivers/gpu/drm/omapdrm/dss/hdmi5_core.c:812:6: warning: variable err set but not used [-Wunused-but-set-variable]

It is not used since commit f5bab2229190 ("OMAPDSS:
HDMI: Add OMAP5 HDMI support")
