drm: Check mode object lease status in all master ioctl paths [v4]
Attempts to modify un-leased objects are rejected with an error.
Information returned about unleased objects is modified to make them
appear unusable and/or disconnected.
Changes for v2 as suggested by Daniel Vetter <daniel.vetter@ffwll.ch>:
* With the change in the __drm_mode_object_find API to pass the
file_priv along, we can now centralize most of the lease-based
access checks in that function.
* A few places sk...
drm: Add drm_object lease infrastructure [v5]
This provides new data structures to hold "lease" information about drm mode
setting objects, and provides for creating new drm_masters which have access to
a subset of the available drm resources.
An 'owner' is a drm_master which is not leasing the objects from another
drm_master, and hence 'owns' them.
A 'lessee' is a drm_master which is leasing objects from some other drm_master.
Each lessee holds the set of objects which it is leasing from ...
drm: Pass struct drm_file * to __drm_mode_object_find [v2]
This will allow __drm_mode_object_file to be extended to perform
access control checks based on the file in use.
v2: Also fix up vboxvideo driver in staging

PM / Runtime: Defer resuming of the device in pm_runtime_force_resume()
When the pm_runtime_force_suspend|resume() helpers were invented, we still
had CONFIG_PM_RUNTIME and CONFIG_PM_SLEEP as separate Kconfig options.
To make sure these helpers worked for all combinations and without
introducing too much of complexity, the device was always resumed in
pm_runtime_force_resume().
More precisely, when CONFIG_PM_SLEEP was set and CONFIG_PM_RUNTIME was
unset, we needed to resume the device as t...

MLK-16757-1 can: flexcan: disable clocks during suspend
Flexcan will be stopped during suspend if no wakeup function required
and enabled after resume accordingly. During this period, we could
explicitly disable clocks.
We do this by moving the clk_prepare_enable/clk_disable_unprepare into
flexcan_chip_start and flexcan_chip_stop functions which will be called
during suspend/resume function.
