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.
