Subject: [PATCH] Revert "leds: save the delay values after a successful call to blink_set()"

This reverts commit 6123b0e274503a0d3588e84fbe07c9aa01bfaf5d.

The problem this patch intends to solve has already been fixed by commit
7a5caabd090b8f7 (drivers/leds/ledtrig-timer.c: fix broken sysfs delay
handling).

Hi, 

A fix for the problem with the delay parameters not being stored is already in
3.1 (and stable). Rather than storing both values at every call to
led_blink_set only the updated value is stored in led_delay_{on,off}_store in
ledtrig-timer.c.

Thanks,
Johan
