mfd: menelaus: Fix possible race condition and leak
[ Upstream commit 9612f8f503804d2fd2f63aa6ba1e58bba4612d96 ]
The IRQ work is added 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 calling menelaus_add_irq_work.
Also, this solves a possible leak as the RTC is never released.
