(kzalloc returns null) Also cleaned up some checks before calls to kfree(). kfree(NULL) is OK.

git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-next Nothing terribly exciting in here probably: - reworked thermal stuff from mupuf/I, has a chance of possibly working well enough when we get to being able to reclock.. - driver will report mmio access faults on chipsets where it's supported - will now sleep waiting on fences on nv84+ rather than polling - some cleanup of the internal fencing, looking towards sli/dmabuf sync - initial support for anx9805 dp/tmds encoder - nv50+ display fixes related to the above, and also might fix a few other issues - nicer error reporting (will log process names with channel errors) - various other random fixes * 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau/linux-2.6: (87 commits) nouveau: ACPI support depends on X86 and X86_PLATFORM_DEVICES drm/nouveau/i2c: add support for ddc/aux, and dp link training on anx9805 drm/nv50: initial kms support for off-chip TMDS/DP encoders drm/nv50-/disp: initial supervisor support for off-chip encoders drm/nv50-/disp: initial work towards supporting external encoders drm/nv50-/kms: remove unnecessary wait-for-completion points drm/nv50-/disp: move DP link training to core and train from supervisor drm/nv50-/disp: handle supervisor tasks from workqueue drm/nouveau/i2c: create proper chipset-specific class implementations drm/nv50-/disp: 0x0000 is a valid udisp config value drm/nv50/devinit: reverse the logic for running encoder init scripts drm/nouveau/bios: store a type/mask hash in parsed dcb data drm/nouveau/i2c: extend type to 16-bits, add lookup-by-type function drm/nouveau/i2c: aux channels not necessarily on nvio drm/nouveau/i2c: fix a bit of a thinko in nv_wri2cr helper functions drm/nouveau/bios: parse external transmitter type if off-chip drm/nouveau: store i2c port pointer directly in nouveau_encoder drm/nouveau/i2c: handle i2c/aux mux outside of port lookup function drm/nv50/graph: avoid touching 400724, it doesn't exist drm/nouveau: Fix DPMS 1 on G4 Snowball, from snow white to coal black. ...

2013-02-20drm/nv50-/kms: remove unnecessary wait-for-completion pointsBen Skeggs
DP link training is now handled as part of the supervisor processing, and can no longer race with it. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-02-20drm/nv50-/disp: move DP link training to core and train from supervisorBen Skeggs
We need to be able to do link training for PIOR-connected ANX9805 from the third supervisor handler (due to script ordering in the bios, can't have the "user" call train because some settings are overwritten from the modesetting bios scripts). This moves link training for SOR-connected DP encoders to the second supervisor interrupt, *before* we call the modesetting scripts (yes, different ordering from PIOR is necessary). This is useful since we should now be able to remove some hacks to workaround races between the supervisor and link training paths. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2013-02-20drm/nv50/devinit: reverse the logic for running encoder init scriptsBen Skeggs
A single U encoder table can match multiple DCB entries, whereas the reverse is not true and can lead to us not matching a DCB entry at all, and fail to initialise some encoders. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-02-20drm/nouveau/bios: store a type/mask hash in parsed dcb dataBen Skeggs

2013-02-20drm/nouveau/i2c: extend type to 16-bits, add lookup-by-type functionBen Skeggs
For off-chip transmitters we won't necessarily have an i2c table entry to lookup, but we can do it instead by encoding the type to include the extdev type and looking that up instead. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2013-02-20drm/nouveau: store i2c port pointer directly in nouveau_encoderBen Skeggs
This is about to become somewhat more complicated to determine in a number of cases, so store the "common" case (DDC/AUX) directly inside the encoder structure. Pre-nv50 code not touched except to fill the pointer, don't care. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-02-20drm/nouveau/i2c: handle i2c/aux mux outside of port lookup functionBen Skeggs
Not quite how I want it yet, but, I'll fix that at some point. For right now, it's needed because find() won't necessarily be used right before a transaction anymore. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
