[Bluez-devel] bluez-gnome: Disable class drop-down when hal is used

[Bastien Nocera]

[-- Attachment #1: Type: text/plain, Size: 262 bytes --]

Heya,

Currently, the class drop-down might be used to override the automatic
class selection when HAL is being used. The simple fix is to not allow
the user to change the adapter's class if HAL is used.

Patch attached.
