From 817890ba15df44181bc9c2bf7527cb066ebae06f Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Fri, 18 Mar 2011 16:52:50 +0000 Subject: [PATCH] MN10300: Use clocksource_register_hz() clocksource_register_hz() calculates the shift/mult pair for the clocksource. Remove the mn10300 duplicate implementation.
