Subject: [media] cx25821-video: remove maxw from cx25821_vidioc_try_fmt_vid_cap
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=66f93178042b6f151552fdb74cbaa2724e59c97c;p=openwrt%2Fstaging%2Fblogic.git

[media] cx25821-video: remove maxw from cx25821_vidioc_try_fmt_vid_cap

After cx25821-video cleanup, this var is not used anymore:

drivers/media/pci/cx25821/cx25821-video.c: In function 'cx25821_vidioc_try_fmt_vid_cap':
drivers/media/pci/cx25821/cx25821-video.c:591:15: warning: variable 'maxw' set but not used [-Wunused-but-set-variable]

as the code now checks the max width as the default case for the
range check.
