Driver core: Make platform_device.id an int
While platform_device.id is a u32, platform_device_add() handles "-1" as a special id value. This has potential for confusion and bugs. Making it an int instead should prevent problems from happening in the future. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
