Pull ACPI fixes from Rafael Wysocki:
"Two fixes for problems introduced recently (ACPICA and the ACPI
backlight driver) and one fix for an older issue that prevents at
least one system from booting.
Specifics:
- Fix an incorrect check introduced by recent ACPICA changes which
causes problems with booting KVM guests to happen, among other
things (Lv Zheng).
- Fix a backlight issue introduced by recent changes to the ACPI
video driver (Aaron Lu).
- Fix the ACPI processor initialization which attempts to register an
IO region without checking if that really is necessary and
sometimes prevents drivers loaded subsequently from registering
their resources which leads to boot issues (Rafael Wysocki)"

ACPI / processor: Avoid reserving IO regions too early

pmu->irq_affinity will not be freed if an error occurred within
arm_pmu_device_probe after of_pmu_irq_cfg has been called.
Note that in the case of_pmu_irq_cfg is returning an error,
pmu->irq_affinity will not be set, but it should be NULL as pmu was

The global variable __oprofile_cpu_pmu is set before the PMU is fully
initialized. If an error occurs before the end of the initialization,
the PMU will be freed and the variable will contain an invalid pointer.
This will result in a kernel crash when perf will be used.
Fix it by moving the setting of __oprofile_cpu_pmu when the PMU is fully
initialized (i.e when it is no longer possible to fail).

The only function called by of_pmu_irq_cfg that will increment the
reference count on dn is of_parse_phandle.
Each time we successfully parse a possible CPU from an
interrupt-affinity property, we increment the refcount of that CPU node
once via of_parse_handle. After validating the CPU is possible, we
decrement the refcount once. Subsequently, we decrement the refcount
again, either as part of an early break if we don't have a matching SPI,
or as part of the end of the loop body.
This will lead to decrementing twice the refcounnt.
Remove the second pairs of call to of_node_put as nobody is using dn
between the first and second call to of_node_put.

Two trivial bugfixes for the atmel-hlcdc driver.
The first one is making use of __drm_atomic_helper_crtc_destroy_state()
instead of duplicating its logic in atmel_hlcdc_crtc_reset() and
risking memory leaks if other objects are added to the common CRTC
state.
The second one is fixing a possible NULL pointer dereference.

"I have accumulated some cleanup patches for HDLCD, partly triggered by
Daniel Vetter's work on non-blocking atomic operations, that I would like
to integrate into v4.7. My first patch is important for the newly enabled
hibernate option for AArch64 on Juno, the others are fixing behaviour in
HDLCD and adding a debugfs entry to help track the underlying framebuffer
usage. I'm also taking one of Daniel's patches from his non-blocking series
to help with the integration of his patches later."
* 'for-upstream/hdlcd' of git://linux-arm.org/linux-ld:
drm: hdlcd: Add information about the underlying framebuffers in debugfs
drm: hdlcd: Cleanup the atomic plane operations
drm/hdlcd: Fix up crtc_state->event handling
drm: hdlcd: Revamp runtime power management

Currently the plane's index is determined by walking the list of all
planes in the mode and finding the position of that plane in the list. A
linear walk, especially a linear walk within a linear walk as frequently
conceived by i915.ko [O(N^2)] quickly comes to dominate profiles.
The plane's index is constant for as long as no earlier planes are
removed from the list. For all drivers, planes are static, determined
at boot and then untouched until shutdown. In fact, there is no locking
provided to allow for dynamic removal of planes/encoders/crtcs.
v2: Convert drm_crtc_index() and drm_encoder_index() as well.
v3: Stop adjusting the indices upon removal; consider the list
construct-only.

Now a drm_pending_event can either send a real drm_event or signal a
fence, or both. It allow us to signal via fences when the buffer is
displayed on the screen. Which in turn means that the previous buffer
is not in use anymore and can be freed or sent back to another driver
for processing.
v2: Comments from Daniel Vetter
- call fence_signal in drm_send_event_locked()
- remove unneeded !e->event check
v3: Remove drm_pending_event->destroy to fix a leak when e->file_priv

Because the HDLCD driver acts as a component master it can end
up enabling the runtime PM functionality before the encoders
are initialised. This can cause crashes if the component slave
never probes (missing module) or if the PM operations kick in
before the probe finishes.
Move the enabling of the runtime PM after the component master
has finished collecting the slave components and use the DRM
atomic helpers to suspend and resume the device.
