drm_gem_object_init() and drm_gem_private_object_init() do exactly the
same (except for shmem alloc) so make the first use the latter to reduce
code duplication.
Also drop the return code from drm_gem_private_object_init(). It seems
unlikely that we will extend it any time soon so no reason to keep it
around. This simplifies code paths in drivers, too.
Last but not least, fix gma500 to call drm_gem_object_release() before
freeing objects that were allocated via drm_gem_private_object_init().
That isn't actually necessary for now, but might be in the future.

Two fixes for memory leaks split into Cedarview and Poulsbo versions,
and a fix for properly setting the pipe base when using fbdev. It's on
my todo-list to start unifying the chips since they are very similar,
but until then I'd like to split them up in case there are side-effects
on Cedarview that I cannot currently test.

The internal crtc cursor gem object pointer was never set/updated since
it was required to be set in the first place.
Fixing this will make the pin/unpin count match and prevent cursor
objects from leaking when userspace drops all references to it. Also
make sure we drop the gem obj reference on failure.

The framebuffer needs to be unpinned in the crtc->disable callback

Old code assumed framebuffer starts at base of stolen memory. Since the
addition of hardware cursors, this might not be true anymore so add the

Two fixes for gma500. First one from Anisse allows us to handle ASLE irqs even
when BIOS doesn't trigger a pipe event irq. The second one allows dual head
setups to have a big shared framebuffer.

By having a higher max resolution we can now set up a virtual
framebuffer that spans several monitors. 4096 should be ok since we're
gen 3 or higher and should be enough for most dual head setups.

Backlight hotkeys weren't working before on certain cedartrail laptops.
The source of this problem is that the hotkeys' ASLE opregion interrupts
were simply ignored. Driver seemed to expect the interrupt to be
associated with a pipe, but it wasn't.
Accepting the ASLE interrupt without an associated pipe event flag fixes
the issue, the backlight code is called when needed, making the
brightness keys work properly.
[patrik: This patch affects irq handling on any netbook with opregion support]

This patch fixes a bug introduced by:
commit 749387dc8d8270b279f27a0a794cdf4f4a4aa774
Author: Patrik Jakobsson <patrik.r.jakobsson@gmail.com>
Date: Sun Apr 7 16:35:50 2013 +0200
drm/gma500: Fix hibernation problems on sdvo encoders
The bug is triggered when we do a mode set on a sdvo encoder with all
connectors in the disconnected state. A crtc is considered enabled by
drm even though all of its connectors are disconnected. Work around
this by adding a check in our sdvo restore function.
Also remove the unneeded dpms on. Prepare and Commit will take care of
that.

This patch fixes build failure of v3.9-rc5 and rc6.

The state of the SDVO chip is more difficult to save than the LVDS so we do a

This patch activates the rebuilding of the gtt. Currently we reinitialize the

i2c_del_adapter() always returns 0. So all checks testing whether it will be
non zero will always evaluate to false and the conditional code is dead code.
This patch updates all callers of i2c_del_mux_adapter() to ignore the return
value and assume that it will always succeed (which it will). In a subsequent
patch the return type of i2c_del_adapter() will be made void.

This should be done in the drivers for two reasons:
- it gets in the way of fastboot efforts
- it links the fb helpers with the crtc helpers instead of going
through the real interface vfuncs, forcing i915 to fake all the
->disable callbacks used by the crtc helper to avoid ugly Oopsen
