The patch titled
leds driver for HP harddisk protection LED
has been removed from the -mm tree. Its filename was
leds-driver-for-hp-harddisk-protection-led.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

Subject: leds driver for HP harddisk protection LED
From: Pavel Machek <pavel@xxxxxxx>
HP notebooks contain accelerometer-based disk protection subsystem, and
LED that indicates hard disk is protected. This is driver for the LED
part.
