xen kconfig: don't "select INPUT_XEN_KBDDEV_FRONTEND"
The Xen framebuffer driver selects the xen keyboard driver, so the latter will be built-in if XEN_FBDEV_FRONTEND=y. However, when CONFIG_INPUT is a loadable module, this configuration cannot work. On mainline kernels, the symbol will be enabled but not used, while in combination with a patch I have to detect such useless configurations, we get the expected link failure: drivers/input/built-in.o: In function `xenkbd_remove': xen-kbdfront.c:(.text+0x2f0): undefined reference to `input_unregister_device' xen-kbdfront.c:(.text+0x30e): undefined reference to `input_unregister_device' This removes the extra "select", as it just causes more trouble than it helps. In theory, some defconfig file might break if it has XEN_FBDEV_FRONTEND in it but not INPUT_XEN_KBDDEV_FRONTEND. The Kconfig fragment we ship in the kernel (kernel/configs/xen.config) however already enables both, and anyone using an old .config file would keep having both enabled.
