Subject: [Patch] [mm] Fix bus_rescan_devices() in -mm
With the __must_check changes in the driver core,
bus_rescan_devices_helper() now returns the return code of its call to
device_attach(). device_attach() will return < 0 on error, 0 on no
match and 1 on match. This means that bus_rescan_devices() will stop
after the first successful match for a device, which is probably not
what we want. Stopping on error makes sense, however.
