Subject: [PATCH 23/31] media: vidtv: cleanup PSI table header function
Date: Tue, 24 Nov 2020 12:06:19 +0100 [thread overview]
Message-ID: <2169ee8f40e97b70fab8efe920db9eda16ae1b73.1606215584.git.mchehab+huawei@kernel.org> (raw)
In-Reply-To: <cover.1606215584.git.mchehab+huawei@kernel.org>
- Pass struct header_write_args as a pointer, instead of
passing as a var;
- Initialize the psi_args struct only once.
