Subject: [media] V4L: Add camera image stabilization control
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=82b3056c5a77b687097bd7f36a598a0b37af24a2;p=linux-beck.git

[media] V4L: Add camera image stabilization control

Add V4L2_CID_IMAGE_STABILIZATION control for the camera image
stabilization feature. This control can be used to enable/disable
image stabilization. It might get converted to a menu control
in future if more options are needed.
