UWB Kconfig: cannot set UWB to N in gconfig

UWB Kconfig: cannot set UWB to N in gconfig

[Richard Kennedy]

I sometimes use 'make gconfig' and I noticed that I cannot disable the
UWB option -- it just won't let me set it to N.

AFAICT this is because the CONFIG USB_WUSB selects UWB which forces it
on.
applying this patch fixes the issue but I'm not sure if this is the
right way to go about it.

any thoughts?

Richard

Not specific to 'gconfig'.

Yes.

UWB can be disabled by disabling both of these options that are several
entries below it in the same menu:

USB_WHCI_HCD and USB_HWA_HCD

and then returning to UWB and disabling it.

Should users have to figure that out?  no.

thanks,
although it's not easy to figure out how to disable this in gconfig.
USB_WHCI_HCD & USB_HWA_HCD end up under a different menu
(drivers/usb/host). 
If you don't know that they exist, all you see is the options under UWB
set to M and gconfig doesn't let you turn them off.  

Here's another version of the patch that changes them all to 'depends
on'. This lets gconfig do the right thing :)

NAK.  It's not sufficiently obvious to a user that Wireless USB support
requires UWB.

This is really an issue with the configuration application.  Consider
improving them to allow switching off select'ed options and popping up a
dialog that says "switching off UWB will also switch off WUSB" etc.
