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 standard
mc146818_get_time().
The second patch renames a function in arch/x86/kernel/rtc.c.
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.
Tested on 3 computers, and on i386 and amd64 VMs.
