Subject: choice =y selection becomes lost after having multiple entries =m with depends on
Date: Wed, 23 Oct 2013 12:51:42 +0200	[thread overview]
Message-ID: <5267AA3E.1040003@linutronix.de> (raw)

Hi,

in USB gadget menu (that is Device Drivers ---> USB support ---> USB
Gadget Support --->  USB Gadget Drivers) I can create a configuration
which is "lost". Here is how to reproduce it:

- first config two gadgets as M:
 <M>   USB Gadget Drivers
 <M>     Audio Gadget
 <M>     Ethernet Gadget
 <M>     MIDI Gadget

 save config & leave

- now start menu config again and go to the same menu, now select
  built-in:
  <*>   USB Gadget Drivers (Ethernet Gadget
  the ethernet gadget is chosen automatically because we can have only
  one gadget selected.
  save config & leave

- step three, go back to the menu and you will see that everything is
  as it was (the <*> is ignored).

With only Audio & Ethernet =m and Midi =n then the switch to =y
behaves differently: The menu looks correct (=y) but the .config keeps
the Audio gadget as =M and it is built. Having multiple entries =m
which have no "depends on" behaves correctly.

So the problem exists only if the item itself has a "depends on" line.
Anyone aware of such kconfig limitation?

Sebastian
