+Subject: drivers: uio: Fix UIO device registration failure
+
+From: Damian Hobson-Garcia <dhobsong@igel.co.jp>
+
+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.
