From 40565f1962c5be9b9e285e05af01ab7771534868 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Mon, 12 Feb 2007 00:52:31 -0800 Subject: [PATCH] Char: timers cleanup - Use timer macros to set function and data members and to modify expiration time. - Use DEFINE_TIMER for global timers and do not init them at run-time in these cases. - del_timer_sync is common in most cases -- we want to wait for timer function if it's still running.
