Subject: media: v4l2-ctrl: Add new helper v4l2_ctrl_ptr_create
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=2e8db63e1f64b6085cc84a03484213af565c81fb;p=openwrt%2Fstaging%2Fblogic.git

media: v4l2-ctrl: Add new helper v4l2_ctrl_ptr_create

This helper function simplifies the code by not needing a union
v4l2_ctrl_ptr and an assignment every time we need to use
a ctrl_ptr.
