Subject[PATCH] drm/bridge: cdns: remove set but not used variable 'bpp'
Date
Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/bridge/cdns-dsi.c: In function
‘cdns_dsi_bridge_enable’:
drivers/gpu/drm/bridge/cdns-dsi.c:788:6: warning: variable ‘bpp’
set but not used [-Wunused-but-set-variable]

It is never used, and so can be removed.
