Subject: Fix bus_rescan_devices() in -mm
From: Cornelia Huck <cornelia.huck@xxxxxxxxxx>
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.
