Hmm. That expression is _really_ hard to figure out.

It would be more logical to make it

	depends on USB_STORAGE && (BLK_DEV_IDE=y || BLK_DEV_IDE=USB_STORAGE)

or, even more preferably, split up the rules as two separate dependencies:

	depends on USB_STORAGE
	depends on BLK_DEV_IDE=y || BLK_DEV_IDE=USB_STORAGE

(where that second thing really _should_ be expressible as

	depends on BLK_DEV_IDE >= USB_STORAGE

but the kconfig language doesn't support that syntax..)
