Subject: [PATCH] media: Fix P010 tiled format description
Date: Sat, 15 Oct 2022 10:56:51 +0200	[thread overview]
Message-ID: <20221015085651.2471818-1-jernej.skrabec@gmail.com> (raw)

There is only 31 bytes of space (without null character) for format
description. P010 tiled format description overflows that for 1
character and warning is generated when used. Fix that by changing Cb to
U and Cr to V, which is also consistent with some other descriptions.

Fixes: 3c8e19d3d3f9 ("media: Add P010 tiled format")
