From e40ec6ff2f42b5516d77a5c34bfa6a9ce45834f4 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Fri, 11 Dec 2009 21:39:51 -0800 Subject: [PATCH] Input: hil-mlc - use del_timer_sync() when unloading the driver del_timer() does not wait for the timer to finish running before returning and therefore is technically not safe. Also make sure to enable tasklet before kicking timer that will schedule it.
