After commit fa1675b (ACPI / PM: Rework and clean up
acpi_dev_pm_get_state()) a NULL pointer dereference will take place
if NULL is passed to acpi_pm_device_sleep_state() as the second
argument.
Fix that by avoiding to use the pointer that may be NULL until
it's necessary to store a return value at the location pointed to
by it (if not NULL).

This reverts commit 160954b7bca43da7cd3cfbce310e6df919a8216e.
This was rearming the workqueue with a 0 timeout, causing
a WARN_ON, and possible loop.
Daniel writes:
"I've looked a bit into this and I think we need to have a separate
work struct for recovering these lost hotplug events since the
continuous self-rearming case is a real risk (e.g. if a connector
flip-flops all the time). At least I don't see a sane way to block out
re-arming with the current code in a simple way. So reverting the
offender seems like the right thing and I'll go back to the drawing
board for 3.12."

Various fbdev changes for 3.11
* xilinxfb updates
* Small cleanups and fixes to multiple drivers

into fbdev/for-next
OMAP display subsystem changes for 3.11 (part 2/2)
This is the second part of OMAP DSS changes for 3.11. This part contains the
new DSS device model support.
The current OMAP panel drivers use a custom DSS bus, and there's a hard limit
of one external display block per video pipeline. In the new DSS device model
the devices/drivers are made according to the control bus of the display block,
usually platform, i2c or spi. The display blocks can also be chained so that we
can have separate drivers for setups with both external encoder and panel.
To allow the current board files, which use the old style panels, to function,
the old display drivers are left in their current state, and new ones are added
to drivers/video/omap2/displays-new/. When the board files have been converted
to use the new style panels, we can remove the old code. This is planned to
happen in v3.12.
Having to support two very different DSS device models makes the driver
somewhat confusing in some parts, and prevents us from properly cleaning up
some other parts. These cleanups will be done when the old code is removed.
The new device model is designed with CDF (Common Display Framework) in mind.
While CDF is still under work, the new DSS device model should be much more
similar to CDF's model than the old device model, which should make the
eventual conversion to CDF much easier.

OMAP display subsystem changes for 3.11 (part 1/2)
This is the first part of OMAP DSS changes for 3.11. This part contains fixes,
cleanups and reorganizations that are not directly related to the new DSS
device model that is added in part 2, although many of the reorganizations are
made to make the part 2 possible.
There should not be any functional changes visible to the user except the few
bug fixes.
The main new internal features:
- Display (dis)connect support, which allows us to explicitly (dis)connect a
whole display pipeline
- Panel list, which allows us to operate without the specific DSS bus
- Combine omap_dss_output to omap_dss_device, so that we have one generic
"entity" for display pipeline blocks

Several drivers need font support independent of CONFIG_VT, cfr. commit
9cbce8d7e1dae0744ca4f68d62aa7de18196b6f4, "console/font: Refactor font
support code selection logic").
Hence move the fonts and their support logic from drivers/video/console/ to
its own library directory lib/fonts/.
This also allows to limit processing of drivers/video/console/Makefile to
CONFIG_VT=y again.

A simple semantic change, when a slave's MAC is cloned by the bond
master then set addr_assign_type to NET_ADDR_STOLEN instead of
NET_ADDR_SET. Also use bond_set_dev_addr() in BOND_FOM_ACTIVE mode
to change the bond's MAC address because the assign_type has to be
set properly.

In struct bonding there's a member called dev_addr_from_first which is
used to denote when the bond dev should clone the first slave's MAC
address but since we have netdev's addr_assign_type variable that is not
necessary. We clone the first slave's MAC each time we have a random MAC
set to the bond device. This has the nice side-effect of also fixing an
inconsistency - when the MAC address of the bond dev is set after its
creation, but prior to having slaves, it's not kept and the first slave's
MAC is cloned. The only way to keep the MAC was to create the bond device
with the MAC address set (e.g. through ip link). In all cases if the
bond device is left without any slaves - its MAC gets reset to a random
one as before.

We have a member called setup_by_slave in struct bonding to denote if the
bond dev has different type than ARPHRD_ETHER, but that is already denoted
in bond's netdev type variable if it was setup by the slave, so use that
instead of the member.

The drm_gem_mmap_obj() has to be protected with dev->struct_mutex,

Now that the code is compatible in semantics, flip the switch.
Use ww_mutex instead of the homegrown implementation.
ww_mutex uses -EDEADLK to signal that the caller has to back off,
and -EALREADY to indicate this buffer is already held by the caller.
ttm used -EAGAIN and -EDEADLK for those, respectively. So some changes
were needed to handle this correctly.

This adds support for a generic reservations framework that can be
hooked up to ttm and dma-buf and allows easy sharing of reservations
across devices.
The idea is that a dma-buf and ttm object both will get a pointer
to a struct reservation_object, which has to be reserved before
anything is done with the contents of the dma-buf.
Changes since v1:
- Fix locking issue in ticket_reserve, which could cause mutex_unlock
to be called too many times.
Changes since v2:
- All fence related calls and members have been taken out for now,
what's left is the bare minimum to be useful for ttm locking conversion.
Changes since v3:
- Removed helper functions too. The documentation has an example
implementation for locking. With the move to ww_mutex there is no
need to have much logic any more.
