      HID: Remove "default m" from HID_LOGITECH_DJ · 6dbea044
      由 Josh Triplett 提交于 
      HID_LOGITECH_DJ uses "default m", which enables it in default kernel
builds.  Since this module just enables extra, non-critical
functionality for one particular piece of hardware (specifically,
differentiating multiple wireless keyboards and mice as separate input
devices rather than treating them as one device), and the hardware works
just fine with the default USB HID support, drop the "default m".

      HID: Allow drivers to be their own listener · 4bc19f62
      由 David Herrmann 提交于 
      hid-picolcd and hid-wiimote do not allow any of hidinput, hiddev or hidraw
to claim the device but still want to remain on the bus. Hence, if a
driver uses the raw_event callback but no other listener claimed the
device, we still leave it on the bus as the driver handles everything by
itself. It thus becomes its own listener.

Under some circumstances (eg., hidinput_connect() fails and raw_event set)
a device may be left on the bus even though it requires external
listeners. But then if hidinput_connect() fails there are bigger issues
than a device that is left unhandled. So we can safely use this heuristic
to avoid adding another flag for special devices like hid-picolcd and
hid-wiimote.

This also removes the ugly hack from hid-picolcd as this is no longer
required.

      HID: usbhid: fix error paths in suspend · eb055fd0
      由 Alan Stern 提交于 
      This patch (as1597) fixes some of the error paths in usbhid's suspend
routine.  The driver was not careful to restart everything that might
have been stopped, in cases where a suspend failed.

For example, once the HID_SUSPENDED flag is set, an output report
submission would not restart the corresponding URB queue.  If a
suspend fails, it's therefore necessary to check whether the queues
need to be restarted.

      HID: usbhid: check for suspend or reset before restarting · d4150c8f
      由 Alan Stern 提交于 
      This patch (as1596) improves the queue-restart logic in usbhid by
checking to see if the device is suspended or a reset is about to
occur.  There's no point submitting an URB if either of those is
true.

      HID: usbhid: replace HID_REPORTED_IDLE with HID_SUSPENDED · f2b5264d
      由 Alan Stern 提交于 
      This patch (as1595) improves the usbhid driver by using the
HID_SUSPENDED bitflag to indicate that the device is suspended rather
than using HID_REPORTED_IDLE, which the patch removes.

Since HID_SUSPENDED was not being used for anything, and since the
name "HID_REPORTED_IDLE" doesn't convey much meaning, the end result
is easier to read and understand.

      HID: usbhid: inline some simple routines · 93101af3
      由 Alan Stern 提交于 
      This patch (as1594) simplifies the usbhid driver by inlining a couple
of routines.  As a result of an earlier patch, irq_out_pump_restart()
and ctrl_pump_restart() are each used in only one place.  Since they
don't really do what their names say, and since they each involve only
about two lines of actual code, there's no reason to keep them as
separate functions.

      HID: usbhid: fix autosuspend calls · 01a7c984
      由 Alan Stern 提交于 
      This patch (as1593) fixes some logic errors in the usbhid driver
relating to runtime PM.  The driver does not balance its calls to
usb_autopm_get_interface_async() and usb_autopm_put_interface_async().

For example, when the control queue is restarted the driver does a
_get.  But the resume won't happen immediately, so the driver leaves
the queue stopped.  When the resume does occur, the queue is restarted
and a second _get occurs, with no balancing _put.

The patch fixes the problem by rearranging the logic for restarting
the queues.  All the _get/_put calls and bitflag settings in
__usbhid_submit_report() are moved into the queue-restart routines.  A
balancing _put call is added for the case where the queue is still
suspended.  A call to irq_out_pump_restart(), which doesn't take all
the right actions for restarting the irq-OUT queue, is replaced by a
call to usbhid_restart_out_queue(), which does.  Similarly for
ctrl_pump_restart().

Finally, new code is added to prevent an autosuspend from happening
every time an URB is cancelled, and the comments explaining what
happens when an URB needs to be cancelled are expanded and clarified.

      HID: usbhid: fix use-after-free bug · 668160e5
      由 Alan Stern 提交于 
      This patch (as1592) fixes an obscure problem in the usbhid driver.
Under some circumstances, a control or interrupt-OUT URB can be
submitted twice.  This will happen if the first submission fails; the
queue pointers aren't updated, so the next time the queue is restarted
the same URB will be submitted again.

The problem is that raw_report gets deallocated during the first
submission.  The second submission will then dereference and try to
free an already-freed region of memory.  The patch fixes the problem
by setting raw_report to NULL when it is deallocated and checking for
NULL before dereferencing it.
