Subject: drivers: uio: Fix UIO device registration failure
From: Damian Hobson-Garcia <[email protected]>
commit 5ed0505c713805f89473cdc0bbfb5110dfd840cb upstream.
Until recently uio_get_minor() returned 0 for success and
a negative value on failure. This became non-negative for suceess and
negative for failure. Restore the original return value spec so that we can
successfully initialize UIO devices with a non-zero minor device
number.
