Subject: [PATCH 04/20] media: drxd: drop offset var from DownloadMicrocode()
Date: Wed, 24 Nov 2021 20:13:07 +0100	[thread overview]
Message-ID: <f4d081b88635e114d69cda30526fa04927be89d2.1637781097.git.mchehab+huawei@kernel.org> (raw)
In-Reply-To: <cover.1637781097.git.mchehab+huawei@kernel.org>

The offset is not needed, and it is never used, as the pointer
itself is already incremented.

So, drop it, in order to solve a W=1 clang warning.
