The SH RTC is a BCD RTC with some version having 4 digits for the year.

The range for the RTCs with only 2 digits for the year was unfortunately
shifted to handle 1999 to 2098.

The IRQ is requested before the struct rtc is allocated and registered, but
this struct is used in the IRQ handler. This may lead to a NULL pointer
dereference.

Switch to devm_rtc_allocate_device/rtc_register_device to allocate the rtc
struct before requesting the IRQ.
