without this fix, xserver will hang on checking input device. i.e . you will find that mouse can't move and monitor can't receive keyboard input too.
remove this patch and boot wrl8 with sato rootfs. xserver will hang on forever. 1:wrlinux-8/wrlinux/configure --enable-board=intel-x86-64 --enable-rootfs=glibc_std-sato --enable-kernel=standard 2: chose a x86-64 target with intel graphic card(meaning requir i915 driver) 3:booting wrlinux, as expect, X11 wil boot and work well. but, you would observe the X11 hang if you remove this commit.
