Subject: [PATCH v9 2/6] media: verisilicon: Do not use ctx fields as format storage when resetting
Date: Mon, 20 Feb 2023 11:48:45 +0100	[thread overview]
Message-ID: <20230220104849.398203-3-benjamin.gaignard@collabora.com> (raw)
In-Reply-To: <20230220104849.398203-1-benjamin.gaignard@collabora.com>

Source and destination pixel formats fields of context structure should
not be used as storage when resetting the format.
Use local variables instead and let hantro_set_fmt_out() and
hantro_set_fmt_cap() set them correctly later.
