USB-serial fixes for 5.4-rc2

Browse source 
Here's a fix for a long-standing issue in the keyspan driver which could
 lead to NULL-pointer dereferences when a device had unexpected endpoint
 descriptors.
 
 Included are also some new device IDs.
 
 All but the last two commits have been in linux-next with no reported
 issues.
