Subject: [PATCH 11/12] media: mt9m001: make VIDIOC_SUBDEV_G_FMT ioctl work with V4L2_SUBDEV_FORMAT_TRY
Date: Sun, 23 Dec 2018 02:12:53 +0900	[thread overview]
Message-ID: <1545498774-11754-12-git-send-email-akinobu.mita@gmail.com> (raw)
In-Reply-To: <1545498774-11754-1-git-send-email-akinobu.mita@gmail.com>

The VIDIOC_SUBDEV_G_FMT ioctl for this driver doesn't recognize
V4L2_SUBDEV_FORMAT_TRY and always works as if V4L2_SUBDEV_FORMAT_ACTIVE
is specified.
