2.6.26-stable review patch.  If anyone has any objections, please let us know.

From: Guillem Jover <guillem.jover@nokia.com>

upstream commit df316e939100e789b3c5d4d102619ccf5834bd00

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.
