From 463e48fa544826898791085508459de246fc4c09 Mon Sep 17 00:00:00 2001 From: Mika Westerberg Date: Tue, 17 Nov 2020 13:19:41 +0300 Subject: thunderbolt: Return -ENOTCONN when ERR_CONN is received This allows the calling code to distinguish if the error was due to ERR_CONN (adapter is disconneced or disabled) or something else.
