Subject: [PATCH v7 2/5] media: verisilicon: Do not use ctx fields as format storage when resetting
Date: Tue, 31 Jan 2023 14:03:24 +0100	[thread overview]
Message-ID: <20230131130327.776899-3-benjamin.gaignard@collabora.com> (raw)
In-Reply-To: <20230131130327.776899-1-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.

Fixes: dc39473d0340 ("media: hantro: imx8m: Enable 10bit decoding")
