Subject: [PATCH] drm/bridge: imx93-mipi-dsi: Fix a couple of building warnings
Date: Tue, 21 Nov 2023 16:56:44 +0800	[thread overview]
Message-ID: <20231121085644.499520-1-victor.liu@nxp.com> (raw)

Fix a couple of building warnings on used uninitialized 'best_m' and
'best_n' local variables by initializing them to zero.  This makes compiler
happy only.  No functional change.

Fixes: ce62f8ea7e3f ("drm/bridge: imx: Add i.MX93 MIPI DSI support")
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202311151746.f7u7dzbZ-lkp@intel.com/
