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 disable_acs_redir parameter stores a pointer to the string passed to
pci_setup(). However, the string passed to PCI setup is actually a
temporary copy allocated in static __initdata memory. After init, once the
memory is freed, it is no longer valid to reference this pointer.
This bug was noticed in v5.0-rc1 after a change in commit c5eb1190074c
("PCI / PM: Allow runtime PM without callback functions") caused
pci_disable_acs_redir() to be called during shutdown which manifested
as an unable to handle kernel paging request at:
RIP: 0010:pci_enable_acs+0x3f/0x1e0

It was also likely possible to trigger this bug when hotplugging PCI
devices.
To fix this, instead of storing a pointer, we use kstrdup() to copy the
disable_acs_redir_param to its own buffer which will never be freed.

[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

When -ENOSPC is returned from pci_alloc_irq_vectors_affinity(),
we still try to allocate multiple irq vectors again, so irq queues
covers the admin queue actually. But we don't consider that, then
number of the allocated irq vector may be same with sum of
io_queues[HCTX_TYPE_DEFAULT] and io_queues[HCTX_TYPE_READ], this way
is obviously wrong, and finally breaks nvme_pci_map_queues(), and
warning from pci_irq_get_affinity() is triggered.
IRQ queues should cover admin queues, this patch makes this
point explicitely in nvme_calc_io_queues().
We got severl boot failure internal report on aarch64, so please
consider to fix it in v4.20.

cancel_delayed_work_sync() was called for any queue, but it should only
be called for the queue that is associated with the currently running job.
Otherwise, if two filehandles are streaming at the same time, then closing the
first will cancel the work which might still be running for a job from the
second filehandle. As a result the second filehandle will never be able to
finish the job and an attempt to stop streaming on that second filehandle will

Currently the IOCTL code clears everything after the per-plane
bytesperline field in struct v4l2_format. The intent was to only clear
the per-plane reserved fields since there is data in struct v4l2_format
after the per-plane format data that userspace may have filled in.

The API of pci_alloc_irq_vectors_affinity() says it returns -ENOSPC if
fewer than @min_vecs interrupt vectors are available for @dev.
However, if a device supports MSI-X but not MSI and a caller requests
@min_vecs that can't be satisfied by MSI-X, we previously returned -EINVAL
(from the failed attempt to enable MSI), not -ENOSPC.
When -ENOSPC is returned, callers may reduce the number IRQs they request
and try again. Most callers can use the @min_vecs and @max_vecs
parameters to avoid this retry loop, but that doesn't work when using IRQ
affinity "nr_sets" because rebalancing the sets is driver-specific.
This return value bug has been present since pci_alloc_irq_vectors() was
added in v4.10 by aff171641d18 ("PCI: Provide sensible IRQ vector
alloc/free routines"), but it wasn't an issue because @min_vecs/@max_vecs
removed the need for callers to iteratively reduce the number of IRQs
requested and retry the allocation, so they didn't need to distinguish
-ENOSPC from -EINVAL.
In v5.0, 6da4b3ab9a6e ("genirq/affinity: Add support for allocating
interrupt sets") added IRQ sets to the interface, which reintroduced the
need to check for -ENOSPC and possibly reduce the number of IRQs requested
and retry the allocation.

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.

we need to revisit the driver architecture to address this

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.
The semantic patch that fixes the first part of this problem is
as follows (http://coccinelle.lip6.fr):
// <smpl>

expression root,e;
local idexpression child;

After a discussion we (me and Boris Brezillon) start to suspect
that this bit does not immediately control the chip select line
at all, it rather enables access to the bank and the hardware
will drive the CS autonomously. If there is a NAND chip connected,
we should keep this enabled.
As fsmc_nand_setup() sets this bit, we can simply remove the
offending code.
