Currently the HID subsystem will create HIDRAW devices for the transport
driver, but it will not disconnect them. Until the HID subsytem gets
fixed, ensure that HIDRAW and HIDDEV devices are disconnected when the
Bluetooth HID device gets removed.

There is a test case in PTS tool; PTS will send the VIRTUAL_CABLE_UNPLUG
command to IUT. Then IUT should disconnect the channel and kill the HID
session when it receives the command. The VIRTUAL_CABLE_UNPLUG command
is parsed by HID transport, but it is not scheduled to do so. Add a
call to hidp_schedule() to kill the session.

With the introduction of CONFIG_DYNAMIC_PRINTK_DEBUG it is possible to

Make a bus from hid core. This is the first step for converting all the
quirks and separate almost-drivers into real drivers attached to this bus.
It's implemented to change behaviour in very tiny manner, so that no driver
needs to be changed this time.
Also add generic drivers for both usb and bt into usbhid or hidp
respectively which will bind all non-blacklisted device. Those blacklisted
will be either grabbed by special drivers or by nobody if they are broken at

According to the bluetooth HID spec v1.0 chapter 7.4.2
"This code requests a major state change in a BT-HID device. A HID_CONTROL
request does not generate a HANDSHAKE response."
"A HID_CONTROL packet with a parameter of VIRTUAL_CABLE_UNPLUG is the only
HID_CONTROL packet a device can send to a host. A host will ignore all other
packets."
So in the hidp_precess_hid_control function, we just need to deal with the
UNLUG packet.

Currently, the freezer treats all tasks as freezable, except for the kernel
threads that explicitly set the PF_NOFREEZE flag for themselves. This
approach is problematic, since it requires every kernel thread to either
set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't
care for the freezing of tasks at all.
It seems better to only require the kernel threads that want to or need to
be frozen to use some freezer-related code and to remove any
freezer-related code from the other (nonfreezable) kernel threads, which is
done in this patch.
The patch causes all kernel threads to be nonfreezable by default (ie. to
have PF_NOFREEZE set by default) and introduces the set_freezable()
function that should be called by the freezable kernel threads in order to
unset PF_NOFREEZE. It also makes all of the currently freezable kernel
threads call set_freezable(), so it shouldn't cause any (intentional)
change of behaviour to appear. Additionally, it updates documentation to
describe the freezing of tasks more accurately.

When cleaning up HIDP sessions, we currently close the ACL connection
before deregistering the input device. Closing the ACL connection
schedules a workqueue to remove the associated objects from sysfs, but
the input device still refers to them -- and if the workqueue happens to
run before the input device removal, the kernel will oops when trying to
look up PHYSDEVPATH for the removed input device.
Fix this by deregistering the input device before closing the
connections.

The current implementation of force feedback for HID devices is
USB-transport only and therefore calling hid_ff_init() from hidp code is
not going to work (plus it creates unwanted dependency of hidp on usbhid).
Remove the hid_ff_init() until either the hid-ff is made
transport-independent, or at least support for bluetooth transport is
added.

I have a bugreport that scrollwheel of bluetooth version of apple
mightymouse doesn't work. The USB version of mightymouse works, as there
is a quirk for handling scrollwheel in hid/usbhid for it.
Now that bluetooth git tree is hooked to generic hid layer, it could easily
use the quirks which are already present in generic hid parser, hid-input,
etc.
Below is a simple patch against bluetooth git tree, which adds quirk
handling to current bluetooth hidp code, and sets quirk flags for device
0x05ac/0x030c, which is the bluetooth version of the apple mightymouse.

This is part of the grand scheme to eliminate the qlen
member of skb_queue_head, and subsequently remove the
'list' member of sk_buff.
Most users of skb_queue_len() want to know if the queue is
empty or not, and that's trivially done with skb_queue_empty()
which doesn't use the skb_queue_head->qlen member and instead
uses the queue list emptyness as the test.

The history of that stuff is often amusing. E.g. for net/core/sock.c

even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
