Subject: [PATCH RFC 06/11] media: vidtv: get rid of some endiannes nonsense
Date:   Mon, 14 Sep 2020 11:03:21 +0200
Message-Id: <47ccbcbd23e44159bbb11274b540d7c2bb66be7c.1600073975.git.mchehab+huawei@kernel.org>

Precedence: bulk

Genmask is always highest order to low order. It doesn't make
any sense to make it depends on endiannes.
