From: Arnd Bergmann <arnd@xxxxxxxx> I came across a randconfig build failure from one driver that only depends on CONFIG_USB_ARCH_HAS_HCD but fails when built without CONFIG_USB: ld: drivers/media/rc/ir_toy.o: in function `irtoy_disconnect': ir_toy.c:(.text+0x24): undefined reference to `usb_kill_urb' ld: ir_toy.c:(.text+0x2c): undefined reference to `usb_free_urb' ld: ir_toy.c:(.text+0x34): undefined reference to `usb_kill_urb' ld: ir_toy.c:(.text+0x3c): undefined reference to `usb_free_urb' Upon a closer look, I find that a lot of the other drivers 'select USB' rather than stating 'depends on USB' as is common for most subsystems. I also find that all except one driver have an extra 'depends on RC_CORE' that is already implied by the top-level 'if RC_CORE' check. Clean up both by reducing the dependencies to the required set.
