On plug-in of my USB-C device, its USB_SS_PORT_LS_SS_INACTIVE
link state bit is set. Greping all the kernel for this bit shows
that the port status requests a warm-reset this way.
This just happens, if its the only device on the root hub, the hub
therefore resumes and the HCDs status_urb isn't yet available.
If a warm-reset request is detected, this sets the hubs event_bits,
which will prevent any auto-suspend and allows the hubs workqueue
to warm-reset the port later in port_event.

No need to initialize the PHY from the driver's probe. It is done by
the core automatically and doing it twice would increment the
phy->powercount counter to 2 instead of 1. During later suspend
operation, the counter will be decremented to one, no phy->power_off()
will occur and worse than that, the following phy->power_on() at
resume time will also be skipped, failing the whole S2RAM operation.

The mvebu xHCI host driver does not have suspend/resume support. Use of
the XHCI_RESET_ON_RESUME quirk is mandatory in order to avoid failures
after resume. This will work only if no USB device is plugged-in.
While at it, mention in the Kconfig file that this IP is also present
on the A3700 SoC.

Current implementation of the USB core does not take into account the

Pull irq fixes from Thomas Gleixner:
"A small set of fixes for the interrupt subsystem:
- Fix a double increment in the irq descriptor allocator which
resulted in a sanity check only being done for every second
affinity mask
- Add a missing device tree translation in the stm32-exti driver.
Without that the interrupt association is completely wrong.
- Initialize the mutex in the GIC-V3 MBI driver
- Fix the alignment for aliasing devices in the GIC-V3-ITS driver so
multi MSI allocations work correctly
- Ensure that the initial affinity of a interrupt is not empty at
startup time.

Pull libnvdimm fixes from Dan Williams:
"A fix for namespace label support for non-Intel NVDIMMs that implement

This has apparently never worked and could wait for v5.1. However it
has enough visibility with hardware vendors [1] and distro bug
trackers [2], and low enough risk that I decided it should go in for
-rc4. The other fixups target the new, for v5.0, nvdimm security
functionality. The larger init path fixup closes a memory leak and a
potential userspace lockup due to missed notifications.

Procedure mlx4_init_user_cqes() handles returns by copy_to_user
incorrectly. copy_to_user() returns the number of bytes not copied.
Thus, a non-zero return should be treated as a -EFAULT error
(as is done elsewhere in the kernel). However, mlx4_init_user_cqes()
error handling simply returns the number of bytes not copied
(instead of -EFAULT).
Note, though, that this is a harmless bug: procedure mlx4_alloc_cq()
(which is the only caller of mlx4_init_user_cqes()) treats any
non-zero return as an error, but that returned error value is processed
internally, and not passed further up the call stack.
In addition, fixes the following sparse warning:
warning: incorrect type in argument 1 (different address spaces)

A few fixes for v5.0.. the opp-level fix and removal of hard-coded irq
name is partially to make things smoother in v5.1 merge window to
avoid dependency on drm vs dt trees, but are otherwise sane changes.

The bindings for Qualcomm opp levels changed after being Acked but
before landing. Thus the code in the GPU driver that was relying on
the old bindings is now broken.
Let's change the code to match the new bindings by adjusting the old
string 'qcom,level' to the new string 'opp-level'. See the patch
("dt-bindings: opp: Introduce opp-level bindings").
NOTE: we will do additional cleanup to totally remove the string from
the code and use the new dev_pm_opp_get_level() but we'll do it in a
future patch. This will facilitate getting the important code fix in
sooner without having to deal with cross-maintainer dependencies.
This patch needs to land before the patch ("arm64: dts: sdm845: Add
gpu and gmu device nodes") since if a tree contains the device tree
patch but not this one you'll get a crash at bootup.

Every GPU core only has one interrupt so there isn't any
value in looking up the interrupt by name. Remove the name (which
is legacy anyway) and use platform_get_irq() instead.

Pull device mapper fixes from Mike Snitzer:
- Fix DM crypt's parsing of extended IV arguments.
- Fix DM thinp's discard passdown to properly account for extra
reference that is taken to guard against reallocating a block before
a discard has been issued.
- Fix bio-based DM's redundant IO accounting that was occurring for
bios that must be split due to the nature of the DM target (e.g.
dm-stripe, dm-thinp, etc).
