Subject[PATCH net] net: hdlc_x25: Return meaningful error code in x25_open
Date
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.

Fixes: f362e5fe0f1f ("wan/hdlc_x25: make lapb params configurable")
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
