From ded017ee6c7b90f7356bd8488f8af1c10ba90490 Mon Sep 17 00:00:00 2001 From: Kishon Vijay Abraham I Date: Tue, 26 Jun 2012 17:40:32 +0530 Subject: usb: phy: fix return value check of usb_get_phy usb_get_phy will return -ENODEV if it's not able to find the phy. Hence fixed all the callers of usb_get_phy to check for this error condition instead of relying on a non-zero value as success condition.
