ACPI: Always report a sync event after a lid state change
Guillem Jover [Thu, 23 Oct 2008 21:28:33 +0000 (00:28 +0300)]
Currently not always an EV_SYN event is reported to userland
after the EV_SW SW_LID event has been sent. This is easy to verify
by using “input-events” from input-utils and just closing and opening
the lid.
