Subject: [media] media: platform: pxa_camera: remove set_selection
X-Git-Tag: v4.14-rc1~332^2~1675
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=226ad6a18f511cfe285cc26a2334cc4257f9ddba;p=platform%2Fkernel%2Flinux-rpi.git

[media] media: platform: pxa_camera: remove set_selection

This is to be seen as a regression as the set_selection (former
set_crop) function is removed. This is a temporary situation in the v4l2
porting, and will have to be added later.
