Pull ACPI fixes from Rafael Wysocki:
"These fix an ACPI initialization ordering issue introduced in the 4.17
time frame and causing functional problems to appear on multiple
systems and fix some fallout of the recent change to enable building
kernels with ACPI support and without PCI.
Specifics:
- Restore the ACPI initialization ordering changed implicitly by the
module-level AML handling rework during the 4.17 development cycle
that caused the EC address space handler based on information from
ECDT to be set up before loading AML definition blocks, making it
effectively not accessible by AML on some systems that don't work
as expected any more (Rafael Wysocki).
- Add direct dependencies on PCI to Kconfig in multiple places for
code that depends on both ACPI and PCI, but the PCI dependency was
implicitly satisfied by the ACPI dependency before, to prevent
invalid configurations from being created, for example by
randconfig (Sinan Kaya)"

When lp55xx_read() fails, "status" is an uninitialized variable and thus
may contain random value; using it leads to undefined behaviors.
The fix inserts a check for the return value of lp55xx_read: if it
fails, returns with its error code.

[Why]
Backlight is conceptually a property of links, not streams.
All backlight programming is done on links, but there is a
stream property bl_pwm_level that is used to restore backlight
on dpms on and s3 resume. This is unnecessary, as backlight
is already restored by hardware with no driver intervention.
[How]
Remove bl_pwm_level, and the stream argument to set_backlight

Some systems have had functional issues since commit 5a8361f7ecce
(ACPICA: Integrate package handling with module-level code) that,
among other things, changed the initial values of the
acpi_gbl_group_module_level_code and acpi_gbl_parse_table_as_term_list
global flags in ACPICA which implicitly caused acpi_ec_ecdt_probe() to
be called before acpi_load_tables() on the vast majority of platforms.
Namely, before commit 5a8361f7ecce, acpi_load_tables() was called from
acpi_early_init() if acpi_gbl_parse_table_as_term_list was FALSE and
acpi_gbl_group_module_level_code was TRUE, which almost always was
the case as FALSE and TRUE were their initial values, respectively.
The acpi_gbl_parse_table_as_term_list value would be changed to TRUE
for a couple of platforms in acpi_quirks_dmi_table[], but it remained
FALSE in the vast majority of cases.
After commit 5a8361f7ecce, the initial values of the two flags have
been reversed, so in effect acpi_load_tables() has not been called
from acpi_early_init() any more. That, in turn, affects
acpi_ec_ecdt_probe() which is invoked before acpi_load_tables() now
and it is not possible to evaluate the _REG method for the EC address
space handler installed by it. That effectively causes the EC address
space to be inaccessible to AML on platforms with an ECDT matching the
EC device definition in the DSDT and functional problems ensue in
there.
Because the default behavior before commit 5a8361f7ecce was to call
acpi_ec_ecdt_probe() after acpi_load_tables(), it should be safe to
do that again. Moreover, the EC address space handler installed by
acpi_ec_ecdt_probe() is only needed for AML to be able to access the
EC address space and the only AML that can run during acpi_load_tables()
is module-level code which only is allowed to access address spaces
with default handlers (memory, I/O and PCI config space).
For this reason, move the acpi_ec_ecdt_probe() invocation back to
acpi_bus_init(), from where it was taken away by commit d737f333b211
(ACPI: probe ECDT before loading AML tables regardless of module-level
code flag), and put it after the invocation of acpi_load_tables() to
restore the original code ordering from before commit 5a8361f7ecce.

The device node iterators perform an of_node_get on each
iteration, so a jump out of the loop requires an of_node_put.
Remote and port also have augmented reference counts, so drop them
on each iteration and at the end of the function, respectively.
Remote is only used for the address it contains, not for the
contents of that address, so the reference count can be dropped
immediately.

Since commit 2bcd3ecab773 when switching mode from X11 (ubuntu mate for
example) the display gets blurry, looking like an invalid framebuffer width.
This commit fixed atomic crtc modesetting in a totally wrong way and
introduced a local unnecessary ->enabled crtc state.
This commit reverts the crctc _begin() and _enable() changes and simply
adds drm_atomic_helper_commit_tail_rpm as helper.

This is to fix missed mmap range check on vGPU bar2 region
and only allow to map vGPU allocated GMADDR range, which means
user space should support sparse mmap to get proper offset for
mmap vGPU aperture. And this takes care of actual pgoff in mmap
request as original code always does from beginning of vGPU
aperture.

When the ioctl interface for the write commands was introduced it did
not mark the core response with UVERBS_ATTR_F_VALID_OUTPUT. This causes
rdma-core in userspace to not mark the buffers as written for valgrind.
Along the same lines it turns out we have always missed marking the driver
data. Fixing both of these makes valgrind work properly with rdma-core and
ioctl.

[Why]
The cursor vanishes when touching the top of edge of the screen for
Raven on Linux.
This occurs because the cursor height is not taken into account when
deciding to disable the cursor.
[How]
Factor in the cursor height into the cursor calculations - and mimic
the existing x position calculations.

[Why]
This fixes a stuttering issue that occurs when moving a hardware cursor
when VRR is enabled.
Previously when VRR is enabled atomic check will grab the connector
state for every atomic update. This has to lock the connector in order
to do so. The locking is bad enough by itself for performance, but
it gets worse with what we do just below that - add all the planes
for the CRTC to the commit.
This prevents the cursor fast path from working - there's more than one
plane now. With state->allow_modeset = true on top of this, it also
adds and removes all the planes from the DC context triggering a full
(very slow) update in DC.
[How]
We need the connector state to get the VRR min/max capbilities, but we
only need them when there's a CRTC mode change or when VRR is toggled.
The condition has been updated accordingly.
