mfd: rc5t583: Fix array subscript is above array bounds
I got below build warning while compiling this driver. It's obviously RC5T583_MAX_INTERRUPT_MASK_REGS is 9 but irq_en_add array only has 8 elements. CC drivers/mfd/rc5t583-irq.o drivers/mfd/rc5t583-irq.c: In function 'rc5t583_irq_sync_unlock': drivers/mfd/rc5t583-irq.c:227: warning: array subscript is above array bounds drivers/mfd/rc5t583-irq.c: In function 'rc5t583_irq_init': drivers/mfd/rc5t583-irq.c:349: warning: array subscript is above array bounds Since the number of interrupt enable registers is 8, this patch adds define for RC5T583_MAX_INTERRUPT_EN_REGS to fix this bug.
