[PATCH net-next] 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.

[PATCH net-next] net: make ndo_get_stats64 a void function
From: Stephen Hemminger <stephen at networkplumber.org> Date: Thu, 5 Jan 2017 09:31:36 -0800> 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 <sthemmin at microsoft.com>You missed at least one new warning, please do a fresh allmodconfig build and watch the logs. drivers/net/ethernet/broadcom/bnx2.c: In function ?bnx2_get_stats64?: drivers/net/ethernet/broadcom/bnx2.c:6830:10: warning: ?return? with a value, in function returning void Thanks.
