Subject: [PATCH v2 2/6] media: v4l: subdev: Rename sub-device state information access functions
Date: Mon, 23 Oct 2023 15:33:04 +0300	[thread overview]
Message-ID: <20231023123308.782592-3-sakari.ailus@linux.intel.com> (raw)
In-Reply-To: <20231023123308.782592-1-sakari.ailus@linux.intel.com>

Rename the sub-devices state information access functions, removing
"_stream" from them. This makes them shorter and so more convenient to
use. No other sets of functions will be needed to access this information.
