Current upstreamed GPIO drivers(showed below) use irq_alloc_generic_chip().
    drivers/gpio/gpio-ml-ioh.c
    drivers/gpio/gpio-mxc.c
    drivers/gpio/gpio-pl061.c
    drivers/gpio/gpio-pch.c
    drivers/gpio/gpio-mxs.c
    drivers/gpio/gpio-sodavil
    drivers/gpio/gpio-omap.c

However, no GPIO driver uses irq_remove_generic_chip().

I'm not familiar with these things. So I'm not sure whether
irq_remove_generic_chip is necessary or not.

Could maintainer or specialist of this tell us the information about it ?

thanks.
