From ba1c8179c3b8e742eee65bc50bdd1396ac763e0e Mon Sep 17 00:00:00 2001 From: Jacek Anaszewski Date: Fri, 20 Nov 2015 16:47:51 +0100 Subject: [PATCH] leds: ipaq-micro: Implement brightness_set_blocking op Since brightness setting can sleep for this driver, implement brightness_set_blocking op, instead of brightness_set. It makes this driver compatible with LED triggers.
