drm/bridge: imx93-mipi-dsi: Fix a couple of building warnings
[ Upstream commit 325b71e820b67569048c621227266783442b75ed ]
Fix a couple of building warnings on used uninitialized 'best_m' and
'best_n' local variables by initializing 'best_m' to zero and 'best_n'
to UINT_MAX. This makes compiler happy only. No functional change.
