Subject: [PATCH AUTOSEL 5.15 35/50] usb: uvc: Enumerate valid values for color matching
Date: Fri, 3 Mar 2023 16:45:16 -0500 [thread overview]
Message-ID: <20230303214531.1450154-35-sashal@kernel.org> (raw)
In-Reply-To: <20230303214531.1450154-1-sashal@kernel.org>
From: Daniel Scally <dan.scally@ideasonboard.com>
[ Upstream commit e16cab9c1596e251761d2bfb5e1467950d616963 ]
The color matching descriptors defined in the UVC Specification
contain 3 fields with discrete numeric values representing particular
settings. Enumerate those values so that later code setting them can
be more readable.
