[PATCH -next] drm/komeda: remove set but not used variable 'old'

From: YueHaibing
Date: Tue Jul 09 2019 - 09:58:28 EST


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

drivers/gpu/drm/arm/display/komeda/komeda_plane.c:
In function komeda_plane_atomic_duplicate_state:
drivers/gpu/drm/arm/display/komeda/komeda_plane.c:161:35:
warning: variable old set but not used [-Wunused-but-set-variable

It is not used since commit 990dee3aa456 ("drm/komeda:
Computing image enhancer internally")
