In case of error, the function devm_ioremap_resource() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check should
be replaced with IS_ERR().

It turns out the dt-probing part of this wasn't tested properly after it
was merged. commit 3aa0582fdb82 ("of: platform: populate /firmware/ node
from of_platform_default_populate_init()") changed the core-code to
generate the platform devices, meaning the driver's attempt fails, and it
bails out.
Fix this by removing the manual platform-device creation for DT systems,
core code has always done this for us.

After finding a "firmware" dt node arm_sdei tries to match it's
compatible string with it. To do so it's calling of_find_matching_node()
which already takes care of decreasing the refcount on the "firmware"
node. We are then incorrectly decreasing the refcount on that node
again.
This patch removes the unwarranted call to of_node_put().

The addresses of NUMA nodes are not printed correctly on i386-PAE
which is misleading.
Here is a debian9-32bit with PAE in a QEMU guest having more than 4G
of memory:
qemu-system-i386 \
-hda /var/lib/libvirt/images/debian32.qcow2 \

-numa node,mem=512M,nodeid=8,cpus=8 \
-numa node,mem=512M,nodeid=9,cpus=9 \

Because of the wrong value type, it prints as below:

The upper half of the start address of the NUMA domains between 6

Fix the value type, to get the correct values in the log as follows:

This patch enables proper interrupts routing between UART module
in Exynos Audio SubSystem and the rest of the SoC. This routing is
completely transparent for UART device and CPU/GIC. UART driver requests
interrupts from the respective controller and enables/masks/handles it
by itself via standard methods.
There are boards (for example TM2), which use UART module in Exynos Audio
SubStem for communication with BlueTooth chip.

In the axp20x driver, the various mfd_cell lists had varying amounts
of indentation, sometimes even within the same list. For the axp288,
there's no alignment at all.
Re-align the right hand side of the assignments with the least amount
of tabs possible. Also collapse the closing bracket and the opening
bracket of the next entry onto the same line for the axp288, to be
consistent with all the other mfd_cell lists.

The tps6586x driver creates an irqchip that is used by its various child
devices for managing interrupts. The tps6586x-rtc device is one of its
children that uses the tps6586x irqchip. When using the tps6586x-rtc as
a wake-up device from suspend, the following is seen:
PM: Syncing filesystems ... done.
Freezing user space processes ... (elapsed 0.001 seconds) done.
OOM killer disabled.
Freezing remaining freezable tasks ... (elapsed 0.000 seconds) done.
Disabling non-boot CPUs ...
Entering suspend state LP1
Enabling non-boot CPUs ...
CPU1 is up
tps6586x 3-0034: failed to read interrupt status
tps6586x 3-0034: failed to read interrupt status
The reason why the tps6586x interrupt status cannot be read is because
the tps6586x interrupt is not masked during suspend and when the
tps6586x-rtc interrupt occurs, to wake-up the device, the interrupt is
seen before the i2c controller has been resumed in order to read the
tps6586x interrupt status.
The tps6586x-rtc driver sets it's interrupt as a wake-up source during
suspend, which gets propagated to the parent tps6586x interrupt.
However, the tps6586x-rtc driver cannot disable it's interrupt during
suspend otherwise we would never be woken up and so the tps6586x must
disable it's interrupt instead.
Prevent the tps6586x interrupt handler from executing on exiting suspend
before the i2c controller has been resumed by disabling the tps6586x
interrupt on entering suspend and re-enabling it on resuming from
suspend.

This function is supposed to return zero on success or negative error
codes on error. Unfortunately, there is a bug so it sometimes returns
non-zero, positive numbers on success.
I noticed this bug during review and I can't test it. It does appear
that the return is sometimes propogated back to _regmap_read() where all
non-zero returns are treated as failure so this may affect run time.

Pull s390 updates from Martin Schwidefsky:
- A larger update for the zcrypt / AP bus code:
+ Update two inline assemblies in the zcrypt driver to make gcc happy
+ Add a missing reply code for invalid special commands for zcrypt
+ Allow AP device reset to be triggered from user space
+ Split the AP scan function into smaller, more readable functions
- Updates for vfio-ccw and vfio-ap
+ Add maintainers and reviewer for vfio-ccw
+ Include facility.h in vfio_ap_drv.c to avoid fragile include chain
+ Simplicy vfio-ccw state machine
- Use the common code version of bust_spinlocks
- Make use of the DEFINE_SHOW_ATTRIBUTE
- Fix three incorrect file permissions in the DASD driver
- Remove bit spin-lock from the PCI interrupt handler
- Fix GFP_ATOMIC vs GFP_KERNEL in the PCI code

idr_find() may fail and return a NULL pointer. The fix checks the return
value of the function and returns an error in case of NULL.

In bnxt_qplib_map_tc2cos(), bnxt_qplib_rcfw_send_message() can return an
error value but it is lost. Propagate this error to the callers.

Drop LIST_HEAD where the variable it declares is never used.
Commit 31c02e215700 ("IPoIB: Avoid using stale last_send counter
when reaping AHs") removed the uses, but not the declaration.
The semantic patch that fixes this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@
identifier x;
@@
- LIST_HEAD(x);
... when != x
// </smpl>

Devfreq framework supports suspend of its devices.
Call the the devfreq interface and allow devfreq devices
preserve/restore their states during suspend/resume.
