Subject: [patch] clocksource: clean up parse_pmtmr()
Date: Sat, 20 Oct 2012 04:46:02 +0000 [thread overview]
Message-ID: <20121020034948.GV5685@mwanda> (raw)
I changed the strict_strtoul() to kstrtouint(). That has the check
for UINT_MAX built in to it so the ifdefs can be removed. Also
I changed a printk() to pr_info().
