[PATCH] drm/bridge: cdns: remove set but not used variable 'nlanes'

From: yu kuai
Date: Thu Dec 26 2019 - 07:15:07 EST


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

drivers/gpu/drm/bridge/cdns-dsi.c: In function âcdns_dsi_mode2cfgâ:
drivers/gpu/drm/bridge/cdns-dsi.c:515:11: warning: variable ânlanesâ
set but not used [-Wunused-but-set-variable]

It is never used, and so can be removed.
