The newer Lenovo ThinkPads have HKEY HID of LEN0068 instead
of IBM0068. Added new HID so that thinkpad_acpi module will
auto load on these newer Lenovo ThinkPads.

The looping helper didn't do anything due to a superficial
semicolon. Furthermore one of the two dump functions suffered
from copy&paste fail.
While staring at the code I've also noticed that the replace
helper (currently unused) is a bit broken.

NV40 and older cards (pre NV50) reserve a vram bo for the vga memory at
card init. This bo is then freed at card shutdown. The problem is that
the ttm bo vram manager was already freed. So a crash occurs when the
vga bo is freed. The fix is to free the vga bo prior to freeing the ttm
bo vram manager. There might be other solutions but this seemed the
simplest to me.

The recent commit closing the race window in device teardown:

Author: James Bottomley <James.Bottomley@suse.de>
Date: Fri Apr 22 10:39:59 2011 -0500
[SCSI] put stricter guards on queue dead checks
is causing a potential NULL deref in scsi_run_queue() because the
q->queuedata may already be NULL by the time this function is called.
Since we shouldn't be running a queue that is being torn down, simply
add a NULL check in scsi_run_queue() to forestall this.

This patch clears PORT_PLC if xhci_bus_resume() resumes a previous suspended
port, because if a port transition from U3 to U0 state, it will report a
port link state change, and software should clear the corresponding PLC bit.
It also uses hcd->speed to check if a port is a USB2 protocol port.
The patch fixes the issue that USB keyboard can not wakeup system from
hibernation.

In the case of missing platform_data we do not hold a spin_lock,
thus we should not call spin_unlock_irqrestore in the error path.
Also simplify the error handling by separating the successful path
from error path. I think this change improves readability.

If cable is not connected to peripheral only board when initializing the
gadget driver, then runtime pm calls are out-of-sync and the musb cannot
idle with omap2430.c. This was noted on Nokia N900 where musb prevented the
CPU to be able to enter deeper retention idle state.
This was working in 2.6.38 before runtime pm conversions but there musb
smart standby/idle modes were configured statically where they are now
updated runtime depending on use and cable status.
Reason for out-of-sync is that runtime pm is activated in function
musb_gadget.c: usb_gadget_probe_driver but suspended only in OTG mode if
cable is not connected when initializing. In peripheral only mode this leads
to out-of-sync runtime pm since runtime pm remain active and is activated
another time in omap2430.c: musb_otg_notifications for VBUS Connect event
and thus cannot suspend for VBUS Disconnect event since the use count remains
active.
Fix this by moving cable status check and pm_runtime_put call in
usb_gadget_probe_driver out of is_otg_enabled block.

Recent runtime pm and hwmod conversions for 2.6.39 broke the musb peripheral
mode OMAP retention idle on boards where the board mode in struct
musb_hdrc_platform_data is set to MUSB_PERIPHERAL.
These conversions changed the way how the OTG_SYSCONFIG register is
configured and used in runtime. Before 2.6.39 smart standby/idle modes were
activated statically in OTG_SYSCONFIG. Those modes allow that the musb is
able to idle when peripheral device is not connected to host.
In 2.6.39 the OTG_SYSCONFIG is updated runtime depending on VBUS status.
No standby/idle modes are used when device is connected and force
standby/idle when disconnected.
Unfortunately VBUS disconnect event that handles the disconnect case lets
the peripheral musb to idle only when board mode is MUSB_OTG. Fix this by
checking the peripheral mode also.

Some v4l drivers currently don't initialize their struct v4l2_subdev
with zeros, and this is a problem since some of the v4l2 code expects
this. One example is the addition of internal_ops in commit 45f6f84,
after that we are at risk of random oopses with these drivers when code
in v4l2_device_register_subdev tries to dereference sd->internal_ops->*,
as can be shown by the report at http://bugs.launchpad.net/bugs/745213
and analysis of its crash at https://lkml.org/lkml/2011/4/1/168
Use kzalloc within problematic drivers to ensure we have a zeroed struct
v4l2_subdev.

The imon_ir_change_protocol function gets called two different ways, one
way is from rc_register_device, for initial protocol selection/setup,
and the other is via a userspace-initiated protocol change request,
either by direct sysfs prodding or by something like ir-keytable.
In the rc_register_device case, the imon context lock is already held,
but when initiated from userspace, it is not, so we must acquire it,
prior to calling send_packet, which requires that the lock is held.
Without this change, there's an easily reproduceable deadlock when
another function calls send_packet (such as either of the display write
fops) after a userspace-initiated change_protocol.
With a lock-debugging-enabled kernel, I was getting this:

Bump the driver version here so its easier to tell if people have this
locking fix or not, and also make locking during probe easier to follow.

firewire: Fix for broken configrom updates in quick succession

Current implementation of ohci_set_config_rom() uses a deferred
bus reset via fw_schedule_bus_reset(). If clients add multiple
unit descriptors to the config_rom in quick succession, the
deferred bus reset may not have fired before succeeding update
requests have come in. This can lead to an incorrect partial
update of the config_rom for both addition and removal of
config_rom descriptors, as the ohci_set_config_rom() routine
will return -EBUSY if a previous pending update has not been
completed yet; the requested update just gets dropped on the floor.
This patch recognizes that the "in-flight" update can be modified
until it has been processed by the bus-reset, and the locking
in the bus_reset_tasklet ensures that the update is done atomically
with respect to modifications made by ohci_set_config_rom(). The
-EBUSY error case is simply removed.
[Stefan R: The bug always existed at least theoretically. But it
became easy to trigger since 2.6.36 commit 02d37bed188c "firewire: core:
integrate software-forced bus resets with bus management" which
introduced long mandatory delays between janitorial bus resets.]

This is the least-bad behaviour. It means that we signal the
vblank event before it actually happens, but since we're disabling
vblanks there's no guarantee that it will *ever* happen otherwise.
This prevents GL applications which use WaitMSC from hanging
indefinitely.

It seems that under certain circumstances the sdhci_tasklet_finish()
call can be entered with mrq set to NULL, causing the system to crash
with a NULL pointer de-reference.
Seen on S3C6410 system. Based on a patch by Dimitris Papastamos.

Currently there is a race in the MMC core between a card-detect
rescan work and the clock-gating work, scheduled from a command
completion. Fix it by removing the dedicated clock-gating mutex
and using the MMC standard locking mechanism instead.
