Subject: [PATCH 1/3] media: omap3isp: Drop custom .unsubscribe_event() handler
Date: Sat,  2 Aug 2025 00:19:31 +0300	[thread overview]
Message-ID: <20250801211933.22553-2-laurent.pinchart@ideasonboard.com> (raw)
In-Reply-To: <20250801211933.22553-1-laurent.pinchart@ideasonboard.com>

The ccdc_unsubscribe_event() and omap3isp_stat_unsubscribe_event()
functions simply call v4l2_event_unsubscribe(), forwarding their
arguments. Replace them with the v4l2_event_subdev_unsubscribe() helper
that performs exactly the same operation.
