Some drivers set PF_NOFREEZE in their kthread functions which is
completely unnecessary and racy - some part of freezer code doesn't
consider cases where PF_NOFREEZE is set asynchronous to freezer
operations.
In general, there's no reason to allow setting PF_NOFREEZE explicitly.
Remove them and change the documentation to note that setting
PF_NOFREEZE directly isn't allowed.

There are still three calls of usb_submit_urb() that will print errors
if those calls return -EPERM or -ENODEV. I have never triggered these,
so I'm not sure when these return values might be seen. It still makes

"device got disconnected" aren't things to worry about).

usb_submit_urb() returns -ENODEV when a usb device is disconnected. In
commit 4935f1c164 ("Bluetooth: btusb: be
quiet on device disconnect") I stopped treating that return as an error
in the three btusb_*_complete() functions.
It turns out btusb_send_frame() generates a similar error if the system
is suspended while the bluetooth usb device is enabled. The sensible
thing to do here seems to be to treat -ENODEV (and -EPERM) just like the
btusb_*_complete() functions now do.

Removed tests which prevent transmission of ACL packets
when the device is in HCI_RAW mode. These tests verified that
there are ACL or LE links currently tracked by the HCI
connection manager. However, a HCI_RAW mode device does not
use the connection manager. In these circumstances, the connection
counts will be zero, and thus, transmitted ACL packets dropped.
The acl_num test is actually a vestige of a previous bulk URB
scheme that is no longer used by this driver (bulk URBs were not
started until at least one ACL connection was created). This was
incompatible with some endpoint implementations and was dropped -
see commit 43c2e57f94.
The utility of these tests is marginal - currently, the hci tx
scheduler cannot send an ACL or LE packet for an untracked connection
(except if the device is in HCI_RAW mode).
Lastly, no other transport layer driver enforces these same tests.
