From bb448f8a60ea93722edb28418448e0008d148b0c Mon Sep 17 00:00:00 2001 From: Chuhong Yuan Date: Fri, 19 Jul 2019 15:36:15 +0800 Subject: [PATCH] net: lan78xx: Merge memcpy + lexx_to_cpus to get_unaligned_lexx Merge the combo use of memcpy and lexx_to_cpus. Use get_unaligned_lexx instead. This simplifies the code. Signed-off-by: Chuhong Yuan Acked-by: Woojung Huh Signed-off-by: David S.
