Description g494074 2015-03-27 21:34:11 UTC 
When trying to execute `libevdev_next_event(dev, LIBEVDEV_READ_FLAG_BLOCKING, &ev)`, the function call fails and prints the following error message:

libevdev error in libevdev_next_event: BUG: invalid flags 0x8

The problem is in line 999 of libevdev.c, which reads

	if (!(flags & (LIBEVDEV_READ_FLAG_NORMAL|LIBEVDEV_READ_FLAG_SYNC|LIBEVDEV_READ_FLAG_FORCE_SYNC))) {

when it should say

	if (!(flags & (LIBEVDEV_READ_FLAG_NORMAL|LIBEVDEV_READ_FLAG_SYNC|LIBEVDEV_READ_FLAG_FORCE_SYNC|LIBEVDEV_READ_FLAG_BLOCKING))) {
