[F][PATCH 0/1] rtc: class: support hctosys from modular RTC drivers

[Wen-chien Jesse Sung]

BugLink: https://launchpad.net/bugs/1952077

== Impact ==
Although we have CONFIG_RTC_HCTOSYS enabled and set CONFIG_RTC_HCTOSYS_DEVICE
to "rtc0", system time would only be set if the RTC driver is built-in. This
may not be an issue on most amd64 systems because CONFIG_RTC_DRV_CMOS is y
for amd64, however it is an issue for other architectures since there may not
be a proper RTC driver enabled as built-in. Also making every RTC driver that
may be used as built-in is not a good option.

== Fix ==
The commit is in mainline since v5.7:

== Risk of Regression ==
It's a clean cherry-pick for v5.4 and looks straight forward so risk should be low.
