6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jiri Kosina jkosina@suse.cz
commit 5b4ffb176d7979ac66b349addf3f7de433335e00 upstream.
This reverts commit 9d1bd9346241cd6963b58da7ffb7ed303285f684.
Multiple people reported misbehaving devices and reverting this commit fixes the problem for them. As soon as the original commit author starts reacting again, we can try to figure out why he hasn't seen the issues (mismatching report descriptors?), but for the time being, fix for 6.7 by reverting.
