staging/olpc: fix dependencies to fix build errors
Fix build errors when GPIO_CS5535=m and FB_OLPC_DCON=y by preventing that kconfig combination. These build errors are caused by having a kconfig bool symbol (FB_OLPC_DCON_1) that depend on a tristate symbol (GPIO_CS5535), but when the tristate symbol is =m, the bool symbol is =y. drivers/built-in.o: In function `dcon_read_status_xo_1': olpc_dcon_xo_1.c:(.text+0x359531): undefined reference to `cs5535_gpio_set' drivers/built-in.o: In function `dcon_wiggle_xo_1': olpc_dcon_xo_1.c:(.text+0x35959f): undefined reference to `cs5535_gpio_set' olpc_dcon_xo_1.c:(.text+0x359610): undefined reference to `cs5535_gpio_clear' drivers/built-in.o:olpc_dcon_xo_1.c:(.text+0x3596a1): more undefined references to `cs5535_gpio_clear' follow drivers/built-in.o: In function `dcon_wiggle_xo_1': olpc_dcon_xo_1.c:(.text+0x359708): undefined reference to `cs5535_gpio_set' drivers/built-in.o: In function `dcon_init_xo_1': olpc_dcon_xo_1.c:(.text+0x35989b): undefined reference to `cs5535_gpio_clear' olpc_dcon_xo_1.c:(.text+0x3598b5): undefined reference to `cs5535_gpio_isset' olpc_dcon_xo_1.c:(.text+0x359963): undefined reference to `cs5535_gpio_setup_event' olpc_dcon_xo_1.c:(.text+0x359980): undefined reference to `cs5535_gpio_set_irq' olpc_dcon_xo_1.c:(.text+0x359a36): undefined reference to `cs5535_gpio_set' Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Cc: Daniel Drake <dsd@laptop.org> Cc: Jens Frederich <jfrederich@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
