Subject: [PATCH 3/8] media: usb: as102: drop as102_dev NULL check
Date: Wed, 24 May 2023 14:11:45 +0200	[thread overview]
Message-ID: <20230524121150.435736-4-hverkuil-cisco@xs4all.nl> (raw)
In-Reply-To: <20230524121150.435736-1-hverkuil-cisco@xs4all.nl>

Fixes this smatch warning:

drivers/media/usb/as102/as102_usb_drv.c:306 as102_usb_release() warn: can 'as102_dev' even be NULL?

And indeed, as102_dev can never be NULL, so just drop the NULL check.
