Subject: [PATCH v6 15/16] media: cvs: Drop comments on sub-device operations
Date: Wed,  1 Jul 2026 15:26:32 +0300	[thread overview]
Message-ID: <20260701122634.1728782-15-sakari.ailus@linux.intel.com> (raw)
In-Reply-To: <20260607215356.842932-1-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.
