[PATCH] media: stm32-dcmi: Drop unnecessary of_match_device() call

From: Rob Herring
Date: Mon Oct 09 2023 - 17:14:15 EST


If probe is reached, we've already matched the device and in the case of
DT matching, the struct device_node pointer will be set. Therefore, there
is no need to call of_match_device() in probe.
