Subject: [PATCH] staging: vc04_services: vchiq_arm: fix error return code of vchiq_release_internal() and vchiq_use_internal()
Date: Sat, 6 Mar 2021 05:22:45 -0800 [thread overview]
Message-ID: <20210306132245.16811-1-baijiaju1990@gmail.com> (raw)
When arm_state is NULL, no error return code of vchiq_release_internal()
and vchiq_use_internal() is assigned.
To fix this bug, ret is assigned with VCHIQ_ERROR.
