Subject: [PATCH v2 1/4] Revert "media: uvcvideo: Set unique vdev name based in type"
Date: Tue, 7 Dec 2021 01:38:37 +0100 [thread overview]
Message-ID: <20211207003840.1212374-2-ribalda@chromium.org> (raw)
In-Reply-To: <20211207003840.1212374-1-ribalda@chromium.org>
A lot of userspace depends on a descriptive name for vdev. Without this
patch, users have a hard time figuring out which camera shall they use
for their video conferencing.
This reverts commit e3f60e7e1a2b451f538f9926763432249bcf39c4.
Cc: <stable@vger.kernel.org>
