From e9d0e7511fda92a6511904996dd0aa57b6d7687a Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Tue, 3 Mar 2020 13:17:16 +0300 Subject: thunderbolt: Fix error code in tb_port_is_width_supported() This function is type bool, and it's supposed to return true on success. Unfortunately, this path takes negative error codes and casts them to bool (true) so it's treated as success instead of failure.
