Subject: Revert "Bluetooth: Enable USB autosuspend by default on btusb"
From: Linus Torvalds <[email protected]>
commit 78794b2cdeac37ac1fd950fc9c4454b56d88ac03 upstream.
This reverts commit 556ea928f78a390fe16ae584e6433dff304d3014.
Jeff Chua reports that it can cause some bluetooth devices (he mentions
an Bluetooth Intermec scanner) to just stop responding after a while
with messages like
[ 4533.361959] btusb 8-1:1.0: no reset_resume for driver btusb?
[ 4533.361964] btusb 8-1:1.1: no reset_resume for driver btusb?
from the kernel. See also
https://bugzilla.kernel.org/show_bug.cgi?id=26182
for other reports.
