Subject: [PATCH v3 5/8] media: v4l: subdev: Make stream argument optional in state access functions
Date: Mon, 23 Oct 2023 20:44:05 +0300 [thread overview]
Message-ID: <20231023174408.803874-6-sakari.ailus@linux.intel.com> (raw)
In-Reply-To: <20231023174408.803874-1-sakari.ailus@linux.intel.com>
The sub-device state access functions take three arguments: sub-device
state, pad and stream. The stream is not relevant for the majority of
drivers and having to specify 0 for the stream is considered a nuisance.
Provide a two-argument macros for these state access functions to cover
the needs of stream-unaware users.
