Subject: [PATCH 07/10] media: i2c: ov9282: drop redundant vblank field
Date: Mon, 14 Sep 2026 21:21:04 +0200 [thread overview]
Message-ID: <20260914-ov9282-fixes-v1-7-f520af59df1b@linux.dev> (raw)
In-Reply-To: <20260914-ov9282-fixes-v1-0-f520af59df1b@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.
