Subject: [PATCH] regulator: rt5190a: check if init_data is NULL, bypass rt5190a_of_parse_cb
Date: Thu, 2 Jun 2022 13:44:06 +0800 [thread overview]
Message-ID: <1654148646-12182-1-git-send-email-u0084500@gmail.com> (raw)
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.
