From a39b9854c79cc9ac7b7b6fed58cf07da23f1f41e Mon Sep 17 00:00:00 2001 From: "Kim, Milo" Date: Wed, 22 Aug 2012 15:32:45 +0800 Subject: leds-lp5523: set the brightness to 0 forcely on removing the driver Turning off the brightness of each channel is required when removing the driver. So use flush_work() rather than cancel_work_sync() to execute remaining brightness works.
