5ed1678206 drm/i915: Move the gtt mm takedown to cleanup
Our VM code already has a cleanup function, and this is a nice place to
put the drm_mm_takedown. This should have no functional impact, it just
leaves the unload function a bit cleaer, and is more logical IMO

Wang, Xiaoming
7585ca0dc9 extcon: remove freed groups caused the panic or warning in unregister flow
(edev->extcon_dev_type.groups) has been freed before device_unregister.
extcon_dev_unregister -> kfree(edev->extcon_dev_type.groups)
then device_unregister -> device_del -> device_remove_attrs
-> device_remove_groups(dev, type->groups);
panic because type->groups has been freed.

This patch is move device_unregister ahead of groups free
to avoid panic in extcon_dev_unregister.

In the case of a device tree system there will be no pdata attached to
the device, causing us to deference a NULL pointer. Better to take the
pdata from the Arizona structure as this will always exist and we know
will have been populated since it is populated by the MFD device which

ad8dbc93a4 staging/lustre/nfs: writing to new files will return ENOENT
This happend with SLES11SP2 Lustre client, which in turn acts as an
NFS server, exporting a subtree of an Lustre fs through NFS.

We detected that whenever we are writing to a new file using, fx,
'echo blah > newfile', it will return ENOENT error. We found
out that this was caused by the anonymous dentry. In SLESS11SP2,
anonymous dentries are assigned '/' as the name, instead of an
empty string. When MDT handles the intent_open call, it will look
up the obj by the name if it is not an empty string, and thus
couldn't find it.

As MDS_OPEN_BY_FID is always set on this request, we never need
to send the name in this request.  The fid is already available
and should be used in case the file has been renamed.

3ce5ae8d46 First set of new features, drivers and cleanups for IIO in the 3.14 cycle.
This mostly consists of patches that didn't quite make the last cycle. Lots
 of interesting things under review currently.
 
 Core:
 - Add devm_iio_device_register/unregister.  I took some convincing on whether
   there would be many devices that really were simple enough to need no
   explicit actions on removal.  Turns out there are some.
 - Move some stray docs to above the relevant implemenation.
 - Drop a redundant repeated check on the fact the trigger has actually changed
   when there is a userspace attempt change it.
 
 Drivers:
 New drivers
 - Freescale MPL3115A2 Pressure / temperature sensor
 
 New functionality
 - hid_sensors: add sensitivity support.
 
 DT bindings
 - tsl2563
 - hmc5843
 
 Cleanups
 - Drop unused scan_type from viperboard adc driver.
 - devm_iio_device_register used in viperboard, ad5421, ad5755, adis16130,
   adxrs450, vcnl4000, adis16220, ad7816, lpc32xx, adt7316, adis16060, isl29018
   and ad2s1200.  Note that this was proposed in a number of other drivers
   and this revealed a number of missorderings in remove functions.  Also for
   now I have blocked this on any device that any hardware suspend suport on
   the basis that we probably want to power down devices if they have no driver
   support loaded.

The old 2420 based H4 is probably not used at all as 2420

of it's large size, and I doubt anybody else is using it either.

We do have minimal omap2420-h4.dts in place, so if anybody wants
more support on H4, patches are welcome.

So let's just remove it as that helps us making mach-omap2 to

The following internal ACPICA header files should be included from
