Subject: [PATCH v2 resend 2/2] x86/rtc: rename mach_set_rtc_mmss
Date:   Tue, 17 May 2022 22:21:31 +0200

Once upon a time, before
commit 3195ef59cb42 ("x86: Do full rtc synchronization with ntp")
in 2013, the function set only the minute and seconds registers
of the CMOS RTC. This is no longer true, so rename the function to
mach_set_cmos_time.
