| Subject: of: mdio: Fix a signedness bug in of_phy_get_and_connect() |
| |
| From: Dan Carpenter <dan.carpenter@oracle.com> |
| |
| [ Upstream commit d7eb651212fdbafa82d485d8e76095ac3b14c193 ] |
| |
| The "iface" variable is an enum and in this context GCC treats it as |
| an unsigned int so the error handling is never triggered. |
| |
| Fixes: b78624125304 ("of_mdio: Abstract a general interface for phy connect") |
