[PATCH v2 resend 0/2] x86/rtc: refactoring

[Mateusz Jończyk]

Hello,

The first and main patch of this series removes duplicated code in
mach_get_cmos_time() in arch/x86/kernel/rtc.c . This function performed
the same thing as mc146818_get_time() - reading the time from the CMOS
RTC - but used a different algorithm. So modify it to use common
mc146818_get_time().

The second patch renames a function in arch/x86/kernel/rtc.c.

Tested originally (on top of 5.18-rc3) on 3 computers, and in i386 and
amd64 VMs.

Greetings,
Mateusz

v2:
  - drop the previously first patch ("rtc-mc146818-lib: reduce RTC_UIP
    polling period"). Its intent was to make behaviour of
    mc146818_get_time() more similar to the existing version of
    mach_get_cmos_time() by decreasing the polling period in
    mc146818_get_time(). However, I determined that this does not matter
    for users of mach_get_cmos_time().

  - use pr_err instead of pr_err_ratelimited in the first remaining
    patch,

  - small patch description modifications.
