It's obviously RC5T583_MAX_INTERRUPT_MASK_REGS is 9 but irq_en_add array only
has 8 elements.

Since the number of interrupt enable registers is 8, this patch adds define for
RC5T583_MAX_INTERRUPT_EN_REGS to fix this bug.

Hi Laxman,
I don't have this hardware, I'd appreciate if you can review and test this patch.
Thank you,
Axel

This looks good. I dont see any issue on this.
I am planning to move this to regmap-irq, probably on next release.
