Subject: [PATCH next] usb: typec: class: Unlocked on error in typec_register_partner()
Date: Tue, 15 Apr 2025 13:45:08 +0300 [thread overview]
Message-ID: <Z_44tOtmml89wQcM@stanley.mountain> (raw)
We recently added some locking to this function but this error path
was accidentally missed. Unlock before returning.
Fixes: ec27386de23a ("usb: typec: class: Fix NULL pointer access")
Signed-off-by: Dan Carpenter <dan.carpenter@linaro.org>
