Subject: [PATCH v2 7/8] media: i2c: ov9282: drop redundant vblank field
Date: Wed, 14 Oct 2026 08:49:14 +0200 [thread overview]
Message-ID: <20261014-ov9282-fixes-v2-7-3bb376d8b1a9@linux.dev> (raw)
In-Reply-To: <20261014-ov9282-fixes-v2-0-3bb376d8b1a9@linux.dev>
The ov9282 main struct has a dedicated vblank field which was only used
to duplicate the value of the vblank v4l2 control.
Therefore drop this struct field.
