Subject: [PATCH v7 13/14] media: cvs: Drop comments on sub-device operations
Date: Fri, 7 Aug 2026 15:24:08 +0300 [thread overview]
Message-ID: <20260807122409.45807-14-sakari.ailus@linux.intel.com> (raw)
In-Reply-To: <20260807122409.45807-1-sakari.ailus@linux.intel.com>
The sub-device operations are well documented in the V4L2 sub-device
framework already. Drop them from the CVS driver.
Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com>
