From: Ivan Ilchenko <Ivan.Ilchenko@oktetlabs.ru>

Change eth_dev_infos_get_t return value from void to int.
Make eth_dev_infos_get_t implementations across all drivers to return
negative errno values if case of error conditions.

This patch needs a respin.

   ../drivers/net/atlantic/atl_ethdev.c
   ../drivers/net/atlantic/atl_ethdev.c:123:12: error: conflicting types for ‘atl_dev_info_get’
    static int atl_dev_info_get(struct rte_eth_dev *dev,
               ^
   ../drivers/net/atlantic/atl_ethdev.c:48:13: note: previous declaration of ‘atl_dev_info_get’ was here
    static void atl_dev_info_get(struct rte_eth_dev *dev,

Looks like the function prototype appears twice in the .c file - I
suggest removing one of them.

Ahh okay.

I wonder if it's possible to get this patch on mainline?

Strange that it went through -next since it's really a fix.

There is a planned early merge end of this week, so it will be in mainline soon.

Not really :) The '-next' name is not used as same as Linux trees and it is
confusing people.

The 'next-X' sub-trees are *not* for the next release, they are sub-trees for
specific subsystem and merged to main repo regularly during a release cycyle and
gets both fixes and features only for this release.
We don't have the concept of the Linux -next trees.
