Subject: [PATCH v2 1/2] net: ethernet: i40e: fix build error

Remove "inline" from __i40e_add_stat_strings.

drivers/net/ethernet/intel/i40e/i40e_ethtool.c: In function
‘__i40e_add_stat_strings’:
drivers/net/ethernet/intel/i40e/i40e_ethtool_stats.h:193:20: error:
function ‘__i40e_add_stat_strings’ can never be inlined because it uses
variable argument lists
 static inline void __i40e_add_stat_strings(u8 **p, const struct
					    i40e_stats stats[],

Signed-off-by: Wang Dongsheng <dongsheng.wang@...-semitech.com>
