ses: requesting a fault indication
commit 2a350cab9daf9a46322d83b091bb05cf54ccf6ab upstream. Noticed that when the sysfs interface of the SCSI SES driver was used to request a fault indication the LED flashed but the buzzer didn't sound. So it was doing what REQUEST IDENT (locate) should do. Changelog: - fix the setting of REQUEST FAULT for the device slot and array device slot elements in the enclosure control diagnostic page - note the potentially defective code that reads the FAULT SENSED and FAULT REQUESTED bits from the enclosure status diagnostic page The attached patch is against git/scsi-misc-2.6 Signed-off-by: Douglas Gilbert <dgilbert@interlog.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
