2016-12-06drm/amdgpu: don't add files at control minor debugfs directoryNicolai Stange
Since commit 8a357d10043c ("drm: Nerf DRM_CONTROL nodes"), a struct drm_device's ->control member is always NULL. In the case of CONFIG_DEBUG_FS=y, amdgpu_debugfs_add_files() accesses ->control->debugfs_root though. This results in a NULL pointer dereference. Fix this by omitting the drm_debugfs_create_files() call for the control minor debugfs directory which is now non-existent anyway.

2016-12-06nvmet: Fix possible infinite loop triggered on hot namespace removalSolganik Alexander
When removing a namespace we delete it from the subsystem namespaces list with list_del_init which allows us to know if it is enabled or not. The problem is that list_del_init initialize the list next and does not respect the RCU list-traversal we do on the IO path for locating a namespace. Instead we need to use list_del_rcu which is allowed to run concurrently with the _rcu list-traversal primitives (keeps list next intact) and guarantees concurrent nvmet_find_naespace forward progress. By changing that, we cannot rely on ns->dev_link for knowing if the namspace is enabled, so add enabled indicator entry to nvmet_ns for that.

2016-12-06dmaengine: ioat: set error code on failuresPan Bian
In function ioat_dma_self_test(), when the calls to dma_mapping_error() fails, the value of return variable err is 0 (indicates no error). As a result, the return value may be inconsistent with the execution status. This patch fixes the bug by assigning -ENOMEM to err on the error path.

2016-12-06drm: Add new driver for MXSFB controllerMarek Vasut
Add new driver for the MXSFB controller found in i.MX23/28/6SX . The MXSFB controller is a simple framebuffer controller with one parallel LCD output. Unlike the MXSFB fbdev driver that is used on these systems now, this driver uses the DRM/KMS framework.

2016-12-06PM / OPP: Don't WARN on multiple calls to dev_pm_opp_set_regulators()Viresh Kumar
If a platform specific OPP driver has called this routine first and set the regulators, then the second call from cpufreq-dt driver will hit the WARN_ON(). Remove the WARN_ON(), but continue to return error in such cases.

2016-12-06PM / OPP: Allow platform specific custom set_opp() callbacksViresh Kumar
The generic set_opp() handler isn't sufficient for platforms with complex DVFS. For example, some TI platforms have multiple regulators for a CPU device. The order in which various supplies need to be programmed is only known to the platform code and its best to leave it to it. This patch implements APIs to register platform specific set_opp() callback.

2016-12-06PM / OPP: Separate out _generic_set_opp()Viresh Kumar
Later patches would add support for custom set_opp() callbacks. This patch separates out the code for _generic_set_opp() handler in order to prepare for that.

2016-12-06PM / OPP: Add infrastructure to manage multiple regulatorsViresh Kumar
This patch adds infrastructure to manage multiple regulators and updates the only user (cpufreq-dt) of dev_pm_opp_set{put}_regulator(). This is preparatory work for adding full support for devices with multiple regulators.
