From: Magnus Damm Date: Mon, 2 Aug 2010 09:24:05 +0000 (+0000) Subject: clocksource: sh_cmt: Rate calculation fix X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=38409d726bc6413d39f082f60bc803f52d8b5849;p=deliverable%2Flinux.git clocksource: sh_cmt: Rate calculation fix Fix the rate calculation in the CMT driver. Without this fix the clocksource runs way too fast and we get a divide-by-zero error.
