Did a bisect which revealed this as 1st bad commit: # git bisect good c78c31b374a68be79cb4a03ef5b6c187f034e903 is the first bad commit commit c78c31b374a68be79cb4a03ef5b6c187f034e903 Author: Saravana Kannan <saravanak@google.com> Date: Tue Apr 28 12:20:05 2020 -0700 Revert "Revert "driver core: Set fw_devlink to "permissive" behavior by default"" This reverts commit 18555cb6db2373b9a5ec1f7572773fd58c77f9ba. The reason[1] for the original revert has now been fixed by commit 00b247557858 ("driver core: Fix handling of fw_devlink=permissive"). So, this patch reverts the revert. Marek has also tested this patch with the fix mentioned above and confirmed that the issue has been fixed.
