4.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hans de Goede <hdegoede@xxxxxxxxxx>
commit f0e8c61110c2c85903b136ba070daf643a8b6842 upstream.
Commit 1fdb92697469 ("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.
