[PATCH] irqchip/renesas-rzv2h: unwind on IRQ setup error

[Cosmin Tanislav]

The call to rzv2h_icu_setup_irqs() may fail after the syscore ops have
been registered and the IRQ domain has been created. In that case, only
the runtime PM usage count is unwound.

Unregister the syscore ops and remove the IRQ domain on this error path.
