From 6f4b67b8ff707147e14ee71045ab25aa286520f2 Mon Sep 17 00:00:00 2001 From: Shin-ichiro KAWASAKI Date: Sun, 21 Jun 2009 10:56:22 +0000 Subject: clocksource: sh_tmu: Make undefined TCOR behaviour less undefined. Avoid undocumented vague TMU behavior when zero value is set to TCOR. This primarily fixes up issues encountered under qemu with a zero-length period, while the hardware itself is fairly ambivalent one way or the other.
