[PATCH v2 2/7] mfd: tqmx86: clear GPIO IRQ resource when no IRQ is set

[Matthias Schiffer]

The driver was registering IRQ 0 when no IRQ was set. This leads to
warnings with newer kernels.

Clear the resource flags, so no resource is registered at all in this
case.

v2: add Fixes line

Andy recommended to use IORESOURCE_DISABLED instead, but this doesn't
have any effect for platform_get_irq(), so I'm resubmitting this patch
without functional changes. Grepping for '\.flags = 0;' shows other
drivers doing the same.
