[PATCH 5.16 0364/1017] memory: emif: check the pointer temp in get_device_details()
From: Greg Kroah-Hartman
Date: Tue Apr 05 2022 - 08:19:27 EST
From: Jia-Ju Bai <baijiaju1990@xxxxxxxxx>
[ Upstream commit 5b5ab1bfa1898c6d52936a57c25c5ceba2cb2f87 ]
The pointer temp is allocated by devm_kzalloc(), so it should be
checked for error handling.
Fixes: 7ec944538dde ("memory: emif: add basic infrastructure for EMIF driver")
