Heiko Carstens 79bc57463b pps gpio client: add missing dependency
Add "depends on GENERIC_HARDIRQS" to avoid compile breakage on s390:

drivers/built-in.o: In function `pps_gpio_remove':
linux-next/drivers/pps/clients/pps-gpio.c:189: undefined reference to `free_irq'

config PPS_CLIENT_KTIMER
tristate "Kernel timer client (Testing client, use for debug)"
help
If you say yes here you get support for a PPS debugging client
which uses a kernel timer to generate the PPS signal.
This driver can also be built as a module. If so, the module
will be called pps-ktimer.
config PPS_CLIENT_LDISC
tristate "PPS line discipline"
depends on PPS
help
If you say yes here you get support for a PPS source connected
with the CD (Carrier Detect) pin of your serial port.
config PPS_CLIENT_PARPORT
tristate "Parallel port PPS client"
depends on PPS && PARPORT
help
If you say yes here you get support for a PPS source connected
with the interrupt pin of your parallel port.
config PPS_CLIENT_GPIO
tristate "PPS client using GPIO"
depends on PPS && GENERIC_HARDIRQS
help
If you say yes here you get support for a PPS source using
GPIO. To be useful you must also register a platform device
specifying the GPIO pin and other options, usually in your board
setup.
