Yes, I do it

I've tested this change, and it works fine.
In the file drivers/clocksource/timer-imx-gpt.c, there is :
#define imx21_gpt_irq_disable imx1_gpt_irq_disable
#define imx21_gpt_irq_enable imx1_gpt_irq_enable
So I think that using imx1 or imx21 has the same result;
Do you think I should put both change in on patch ?
Or is it better to do two patches please ?
Regards,
Philippe
