[PATCH 4/4] drm/omap: Remove set but not used variable 'err' in hdmi4_audio_config

[zhengbin]

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

drivers/gpu/drm/omapdrm/dss/hdmi4_core.c: In function hdmi4_audio_config:
drivers/gpu/drm/omapdrm/dss/hdmi4_core.c:689:6: warning: variable err set but not used [-Wunused-but-set-variable]

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