Subject[PATCH] regulator: rt5190a: check if init_data is NULL, bypass rt5190a_of_parse_cb
Date
From: ChiYuan Huang <cy_huang@richtek.com>

If the node for the match name cannot be found, 'of_regulator_match' will
returns init_data as NULL for this regulator.

Add the check for the init_data. If it's NULL, make 'rt5190a_of_parse_cb'
function directly return.
