From 6ceb0182b087e64b754e3bfbcb4d71d2a51cb052 Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Tue, 18 May 2021 20:49:24 +0300 Subject: [PATCH] net: mdio: provide shim implementation of devm_of_mdiobus_register [ Upstream commit 86544c3de6a2185409c5a3d02f674ea223a14217 ] Similar to the way in which of_mdiobus_register() has a fallback to the non-DT based mdiobus_register() when CONFIG_OF is not set, we can create a shim for the device-managed devm_of_mdiobus_register() which calls devm_mdiobus_register() and discards the struct device_node *. In particular, this solves a build issue with the qca8k DSA driver which uses devm_of_mdiobus_register and can be compiled without CONFIG_OF.
