From bc1f44709cf27fb2a5766cadafe7e2ad5e9cb221 Mon Sep 17 00:00:00 2001 From: stephen hemminger Date: Fri, 6 Jan 2017 19:12:52 -0800 Subject: net: make ndo_get_stats64 a void function The network device operation for reading statistics is only called in one place, and it ignores the return value. Having a structure return value is potentially confusing because some future driver could incorrectly assume that the return value was used. Fix all drivers with ndo_get_stats64 to have a void function. Signed-off-by: Stephen Hemminger Signed-off-by: David S.
