rtc: rx8010: Fix return code for rx8010_probe

2019-12-23T10:16:23+00:00

In the current code, the return value of devm_request_threaded_irq may be
returned. This fixes it.

rtc: rx8010: return meaningful value for RTC_VL_READ

2019-12-18T09:37:45+00:00

RX8010_FLAG_VLF means the voltage dropped too low and data has been lost.

rtc: rx8010: remove RTC_VL_CLR handling

2019-12-18T09:37:44+00:00

Remove RTC_VL_CLR handling because it is a disservice to userspace as it
removes the important information that the RTC data is invalid. This may
lead userspace to set an invalid system time later on.

We have a dedicated pointer for that, so use it. Much easier to read and

rtc: stop validating rtc_time in .read_time

2018-03-02T09:09:58+00:00

The RTC core is always calling rtc_valid_tm after the read_time callback.
It is not necessary to call it just before returning from the callback.

The err variable is not being reset after a successful read. Explicitly
return 0 at the end of function call to account for all return paths.
