V4L/DVB (5163): Add checks for CAP_SYS_ADMIN to VIDIOC_DBG_G_REGISTER Before, root privileges were only needed to set hardware registers, not to read them. On some hardware, reading from the wrong place at the wrong time can hang the machine. So, to be consistent, root privileges are required to read registers on all hardware.
