From 4674a12b650d2a824ab130222bd04eecaa69a9de Mon Sep 17 00:00:00 2001 From: Russell King Date: Tue, 10 Dec 2019 11:28:12 +0000 Subject: net: phylink: propagate phy_attach_direct() return code of_phy_attach() hides the return value of phy_attach_direct(), forcing us to return a "generic" ENODEV error code that is indistinguishable from the lack-of-phy-property case. Switch to using of_phy_find_device() to find the PHY device, and then propagating any phy_attach_direct() error back to the caller.
