Subject: [PATCH 2/3] keyboard,kdb: inject SYN events in kbd_clear_keys_helper

From: Maxim Levitsky <maximlevitsky@...il.com>

The kbd_clear_keys_helper injects the keyup events alright, but it
doesn't inject SYN events, and therefore X evdev driver doesn't pick
these injected events untill next SYN event.
