Regarding unintialized variables

["debian developer" <debiandev@xxxxxxxxx>]

Hello,

Consider the following code snippet...

        const char *type;

        switch (rfkill->type) {
        case RFKILL_TYPE_WLAN:
                type = "wlan";
                break;
        case RFKILL_TYPE_BLUETOOTH:
                type = "bluetooth";
                break;
        case RFKILL_TYPE_UWB:
                type = "ultrawideband";
                break;
        case RFKILL_TYPE_WIMAX:
                type = "wimax";
                break;
        default:
                BUG();
        }


It is clear that type will be set or BUG() called. Why don't we
initialize type to NULL during declaration??

char *type  = NULL;

should fix the warning which i get
warning: 'type' might be used uninitialized in this function

Please let me know so that i can submit a patch for that.

Thanks.
