since V4L1 is no longer provided by the kernel, the user space header has been removed. so udev now build fails: CC extras/udev-acl/extras_udev_acl_udev_acl-udev-acl.o extras/v4l_id/v4l_id.c:31:28: fatal error: linux/videodev.h: No such file or directory compilation terminated. make[2]: *** [extras/v4l_id/v4l_id.o] Error 1 simple fix is to not build that code anymore
Backported v4lv1 removal patch from udev-167.
