Geert Uytterhoeven 501ef0f95a gpio: rcar: Check for irq_set_irq_wake() failures 
If an interrupt controller doesn't support wake-up configuration,
irq_set_irq_wake() returns an error code.  Then any subsequent call
trying to deconfigure wake-up will cause an imbalance, and a warning
will be printed:

    WARNING: CPU: 1 PID: 1341 at kernel/irq/manage.c:540 irq_set_irq_wake+0x9c/0xf8()
    Unbalanced IRQ 26 wake disable

To fix this, refrain from any further parent interrupt controller
(de)configuration if irq_set_irq_wake() failed.

Alternative fixes would be:
  - calling "gic_set_irqchip_flags(IRQCHIP_SKIP_SET_WAKE)" from the
    platform code,
  - setting "gic_chip.flags = IRQCHIP_SKIP_SET_WAKE" in the GIC driver
    code,
but these were withheld as the GIC hardware doesn't really support
wake-up interrupts.

Fixes: ab82fa7da4 ("gpio: rcar: Prevent module clock disable when wake-up is enabled")
