Subject: Re: [PATCH] drivers:pci Add pcie/Kconfig to pci/Kconfig

Hi Bjorn,
I just sent a patch regarding pcie Kconfig in arch/ . I just wanted to ask how did you get these errors you pasted:

>  drivers/pci/pcie/Kconfig:61:warning: choice value used outside its choice group
>  drivers/pci/pcie/Kconfig:67:warning: choice value used outside its choice group
>  drivers/pci/pcie/Kconfig:74:warning: choice value used outside its choice group


Is there a tool for this ? I just wanted to be better at debugging kernel compilation process.

Thanks, Sasa
