The patch titled
rtc-x1205: unconditionally set date when setting clock
has been removed from the -mm tree. Its filename was
rtc-x1205-unconditionally-set-date-when-setting-clock.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

Subject: rtc-x1205: unconditionally set date when setting clock
From: Johannes Weiner <jw@xxxxxxxxx>
All callsites of x1205_set_datetime() want the date to be set as well, so
remove the flag parameter and set it unconditionally.
