From 85dc6ee1237c8a4a7742e6abab96a20389b7d682 Mon Sep 17 00:00:00 2001 From: Dinh Nguyen Date: Tue, 10 Dec 2013 19:49:18 +0100 Subject: [PATCH] clocksource: dw_apb_timer_of: Fix read_sched_clock The read_sched_clock should return the ~value because the clock is a countdown implementation. read_sched_clock() should be the same as __apbt_read_clocksource().
