[PATCH 5/7] [media] gspca: add INPUT dependency

[Arnd Bergmann]

The gspca  driver uses the input_event infrastructure and fails
to link if that is not available:

drivers/built-in.o: In function `gspca_disconnect':
media/usb/gspca/gspca.c:2171: undefined reference to `input_unregister_device'
drivers/built-in.o: In function `gspca_dev_probe2':
media/usb/gspca/gspca.c:2112: undefined reference to `input_allocate_device'
media/usb/gspca/gspca.c:2112: undefined reference to `input_register_device'
media/usb/gspca/gspca.c:2112: undefined reference to `input_unregister_device'
media/usb/gspca/gspca.c:2112: undefined reference to `input_free_device'
drivers/built-in.o: In function `sd_int_pkt_scan':
media/usb/gspca/pac207.c:428: undefined reference to `input_event'
drivers/built-in.o: In function `sd_int_pkt_scan':
media/usb/gspca/pac7302.c:879: undefined reference to `input_event'
drivers/built-in.o: In function `sd_int_pkt_scan':
media/usb/gspca/se401.c:612: undefined reference to `input_event'
drivers/built-in.o: In function `sd_stop0':
media/usb/gspca/xirlink_cit.c:2742: undefined reference to `input_event'
drivers/built-in.o: In function `cit_check_button':
media/usb/gspca/xirlink_cit.c:2935: undefined reference to `input_event'
drivers/built-in.o:/git/arm-soc/include/linux/input.h:414: more undefined references to `input_event' follow

This adds an explicit dependency.
