Subject: [PATCH v5 01/15] media: streamzap: Add missing rc_unregister_device()
Date: Wed, 29 Jul 2026 16:22:39 +0100 [thread overview]
Message-ID: <96fd93385f18492cdafaa964e91e82671fc62fc9.1785338381.git.sean@mess.org> (raw)
In-Reply-To: <cover.1785338381.git.sean@mess.org>
If usb_submit_urb() fails during probe, then the error path is missing a
call to rc_unregister_device(), which will leak various things like the
input device.
Fixes: 42844992664f ("media: rc: streamzap: Error handling in probe")
