Browse Source 
This includes following USB4/Thunderbolt fixes for v6.7-rc6:
 
   - Fix memory leak in margining_port_remove()
   - Correct minimum bandwidth allocated for USB 3.x and PCIe to avoid
     reducing DisplayPort capabilities in certain monitor configurations.
 
 Both have been in linux-next with no reported issues.
