Precedence: bulk

This reverts commit fb1316b0ff3fc3cd98637040ee17ab7be753aac7.

As today, the minimum version of GCC required to build the kernel is
5.1, which does not support static const structure initialization.

Error:
drivers/media/usb/uvc/uvc_ctrl.c:737:2: error: initializer element is not a compile-time constant

Fixes: fb1316b0ff3f ("media: uvcvideo: Fix power line control for Lenovo Integrated Camera")
