Subject: [REVIEW PATCH 07/12] em28xx: remove ioctl VIDIOC_CROPCAP
Date: Fri, 25 Jan 2013 18:26:57 +0100 [thread overview]
Message-ID: <1359134822-4585-8-git-send-email-fschaefer.oss@googlemail.com> (raw)
In-Reply-To: <1359134822-4585-1-git-send-email-fschaefer.oss@googlemail.com>
The em28xx driver doesn't support the VIDIOC_G_CROP and VIDIOC_S_CROP ioctls,
so VIDIOC_CROPCAP is useless and has the potential to confuse applications,
because it can be interpreted as indicator for cropping support.
