Subject: [media] v4l2-ctrl: move function prototypes from common.h to ctrls.h
X-Git-Tag: v4.9.8~4959^2~135
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=79fbc209f11b82d8cad37e20da71851fdceecfbd;p=platform%2Fkernel%2Flinux-rpi3.git

[media] v4l2-ctrl: move function prototypes from common.h to ctrls.h

For some unknown reason several control prototypes where in v4l2-common.c
instead of in v4l2-ctrls.h. Move them and document them.
