Subject: set_rtc_mmss: show warning message only once
X-Git-Tag: v2.6.38-rc1~379
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3e5c12409c54c30f1d1b16bba5d4d24e35aa283c;p=pandora-kernel.git

set_rtc_mmss: show warning message only once

Occasionally the system gets into a state where the CMOS clock has gotten
slightly ahead of current time and the periodic update of RTC fails.  The
message is a nuisance and repeats spamming the log.

  See: http://www.ntp.org/ntpfaq/NTP-s-trbl-spec.htm#Q-LINUX-SET-RTC-MMSS

Rather than just removing the message, make it show only once and reduce
severity since it indicates a normal and non urgent condition.
