Subject: [PATCH] leds: Fix uninitialized variable 'ret' in mt6370_mc_pattern_clear

Fix the uninitialized symbol 'ret' in the function mt6370_mc_pattern_clear
to resolve the following warning:
drivers/leds/rgb/leds-mt6370-rgb.c:604 mt6370_mc_pattern_clear()
error: uninitialized symbol 'ret'.
Initialize 'ret' to 0 to prevent undefined behavior from uninitialized
access.
