Alexandre Belloni 82663f99cb rtc: pl030: fix possible race condition
[ Upstream commit c778ec8582 ]

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
before requesting the IRQ.
