Commit 55a9c95d70ab ("Bluetooth: btusb: Use DMI matching for QCA reset_resume quirking"), added the Lenovo Yoga 920 to the btusb_needs_reset_resume_table.
Testing has shown that this is a false positive and the problems where caused by issues with the initial fix: commit fd865802c66b ("Bluetooth: btusb: fix QCA Rome suspend/resume"), which has already been reverted.
So the QCA Rome BT in the Yoga 920 does not need a reset-resume quirk at all and this commit removes it from the btusb_needs_reset_resume_table.
Note that after this commit the btusb_needs_reset_resume_table is now empty. It is kept around on purpose, since this whole series of commits started for a reason and there are actually broken platforms around, which need to be added to it.
This is hilarious.
The platform at my hand still needs the quirk though, so the table is quite useful. I’ll send a patch soon.
I think we need to go back to the author(s) of commit fd865802c66b and find proper details about said "numerous reported instances" of problems... Anyway:
