Subject: [PATCH 1/3] media: ov2640: set default window and format code at probe time
Date: Sat, 8 Dec 2018 13:44:44 +0900 [thread overview]
Message-ID: <1544244286-11597-2-git-send-email-akinobu.mita@gmail.com> (raw)
In-Reply-To: <1544244286-11597-1-git-send-email-akinobu.mita@gmail.com>
Set default window and format code at probe time instead of always checking
if they have not been set yet when VIDIOC_SUBDEV_G_FMT ioctl is called.
This change simplifies the next patch (make VIDIOC_SUBDEV_G_FMT ioctl work
with V4L2_SUBDEV_FORMAT_TRY).
