ahci: add Acer G725 to broken suspend list
Acer G725 shares the same suspend problem with the HP laptops which lose ATA devices on resume. New firmware which fixes the problem is already available. Add G725 with old firmwares to the broken suspend list. This problem has been reported in bko#15104. http://bugzilla.kernel.org/show_bug.cgi?id=15104 Signed-off-by: Tejun Heo <tj@kernel.org> Reported-by: Jani-Matti H├Ątinen <jani-matti.hatinen@iki.fi> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
