Subject: [PATCH 22/31] media: vidtv: cleanup PSI descriptor write function
Date: Tue, 24 Nov 2020 12:06:18 +0100 [thread overview]
Message-ID: <9e0d29e2b7dbc232ae5176a43dae9ef40932b994.1606215584.git.mchehab+huawei@kernel.org> (raw)
In-Reply-To: <cover.1606215584.git.mchehab+huawei@kernel.org>
This function initializes the psi_args twice, and receives
a struct, instead of a pointer to a struct.
Clean it up.
