-Subject: [PATCH] net: add devm version of alloc_etherdev_mqs function
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This patch adds devm_alloc_etherdev_mqs function and devm_alloc_etherdev
-macro. These can be used for simpler netdev allocation without having to
-care about calling free_netdev.
-
-Thanks to this change drivers, their error paths and removal paths may
-get simpler by a bit.
