Subject: [PATCH v11 3/9] media: hantro: change hantro_codec_ops run prototype to return errors
Date: Tue, 25 May 2021 18:12:32 +0200	[thread overview]
Message-ID: <20210525161238.1191168-4-benjamin.gaignard@collabora.com> (raw)
In-Reply-To: <20210525161238.1191168-1-benjamin.gaignard@collabora.com>

Change hantro_codec_ops run prototype from 'void' to 'int'.
This allows the driver to cancel the job if an error occurs while configuring
the hardware.

Subject: [PATCH v11 3/9] media: hantro: change hantro_codec_ops run prototype to return errors
Date: Tue, 25 May 2021 18:12:32 +0200	[thread overview]
Message-ID: <20210525161238.1191168-4-benjamin.gaignard@collabora.com> (raw)
In-Reply-To: <20210525161238.1191168-1-benjamin.gaignard@collabora.com>

Change hantro_codec_ops run prototype from 'void' to 'int'.
This allows the driver to cancel the job if an error occurs while configuring
the hardware.
