rtc: cpcap: fix range

2020-07-02T20:32:00+00:00

Unbreak CPCAP driver, which has one more bit in the day counter
increasing the max. range from 2014 to 2058. The original commit
introducing the range limit was obviously wrong, since the driver
has only been written in 2017 (3 years after 14 bits would have
run out).

rtc: cpcap: set range

2020-03-16T10:12:10+00:00

The CPCAP rtc is a 14bit day counter plus a 17bit seconds counter.

Note that this failed on Nov 10 2014 so it is very likely this driver as
never been used since.

This patch was build-tested on 20 different arch-es.

It also makes these drivers SubmitChecklist#1 compliant.

rtc: cpcap: stop validating rtc_time in .read_time

2018-03-02T09:09:59+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.

rtc: cpcap: fix improper use of IRQ_NONE for request_threaded_irq

2017-04-14T10:08:52+00:00

There's a funny typo where IRQ_NONE is used instead of IRQF_TRIGGER_NONE
for request_threaded_irq(). Let's fix it before it gets copied elsewhere.

We shouldn't kfree(rtc) because is devm_ managed memory.  It leads to a
double free.
