Driver core fix for 5.8-rc7 

Here is a single driver core fix for 5.8-rc7.  It resolves a problem
 found in the previous fix for this code made in 5.8-rc6.  Hopefully this
 is all now cleared up, as this seems to be the last of the reported
 issues in this area, and was tested on the problem hardware.
 
 This patch has been in linux-next with no reported problems.
