From a4eef43a120d51bb5386730b820704e5cb5e1acf Mon Sep 17 00:00:00 2001 From: Chuanhong Guo Date: Sat, 15 Dec 2018 00:03:43 +0800 Subject: [PATCH] ath79: ag71xx: replace alloc_etherdev with devm_alloc_etherdev using the devm api makes the code simpler. also drop unneeded memory free from ag71xx_remove since they are allocated using devm apis.
