From 81b8be68ef8e8915d0cc6cedd2ac425c74a24813 Mon Sep 17 00:00:00 2001 From: Xie He Date: Tue, 2 Feb 2021 23:15:41 -0800 Subject: [PATCH] net: hdlc_x25: Return meaningful error code in x25_open It's not meaningful to pass on LAPB error codes to HDLC code or other parts of the system, because they will not understand the error codes. Instead, use system-wide recognizable error codes.
