Subject: [PATCH] net: add devm version of alloc_etherdev_mqs function
|
|
|
|
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.
