question about arch/arm/mach-h720x/include/mach/irqs.h

[Julia Lawall]

The file arch/arm/mach-h720x/include/mach/irqs.h contains the following 
code:

/* Enable mask for multiplexed interrupts */
#define IRQ_ENA_MUX	(1<<IRQ_TIMERX) | (1<<IRQ_GPIOA) | (1<<IRQ_GPIOB) | \
 			(1<<IRQ_GPIOC) 	| (1<<IRQ_GPIOD) | (1<<IRQ_GPIOE) | \
 			(1<<IRQ_TIMERX)

This code includes the expression (1<<IRQ_TIMERX) twice.  Could the second 
(1<<IRQ_TIMERX) just be dropped, or was something else intended?

thanks,
julia
