4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Matjaz Hegedic <matjaz.hegedic@xxxxxxxxx> [ Upstream commit 3b3e78552d3077ec70d2640e629e07e3ab416a6a ] Without the parameter reboot=a, ASUS EeeBook X205TA/W will hang when it should reboot. This adds the appropriate quirk, thus fixing the problem.
