Subject: [PATCH v2] firmware: arm_scmi: Fix to replace of_match_device
Date: Fri, 22 Mar 2019 16:55:03 -0500 [thread overview]
Message-ID: <20190322215503.13434-1-pakki001@umn.edu> (raw)
of_match_device can return NULL if no matching device is found.
This patch replaces the function with of_device_get_match_data.
and returns -EINVAL in such a scenario.
