Pull RISC-V updates from Paul Walmsley:
"A few minor RISC-V updates for v5.3-rc4:
- Remove __udivdi3() from the 32-bit Linux port, converting the only
upstream user to use do_div(), per Linux policy
- Convert the RISC-V standard clocksource away from per-cpu data
structures, since only one is used by Linux, even on a multi-CPU
system
- A set of DT binding updates that remove an obsolete text binding in
favor of a YAML binding, fix a bogus compatible string in the
schema (thus fixing a "make dtbs_check" warning), and clarifies the
future values expected in one of the RISC-V CPU properties"

Pull driver core fixes from Greg KH:
"Here are two small fixes for some driver core issues that have been
reported. There is also a kernfs "fix" here, which was then reverted
because it was found to cause problems in linux-next.
The driver core fixes both resolve reported issues, one with gpioint
stuff that showed up in 5.3-rc1, and the other finally (and hopefully)
resolves a very long standing race when removing glue directories.
It's nice to get that issue finally resolved and the developers
involved should be applauded for the persistence it took to get this
patch finally accepted.
All of these have been in linux-next for a while with no reported
issues. Well, the one reported issue, hence the revert :)"

Pull tty fix from Greg KH:
"Here is a single tty kgdb fix for 5.3-rc4.
It fixes an annoying log message that has caused kdb to become
useless. It's another fallout from commit ddde3c18b700 ("vt: More
locking checks") which tries to enforce locking checks more strictly
in the tty layer, unfortunatly when kdb is stopped, there's no need
for locks :)
This patch has been linux-next for a while with no reported issues"

Pull USB fixes from Greg KH:
"Here are some small USB fixes for 5.3-rc4.
The "biggest" one here is moving code from one file to another in
order to fix a long-standing race condition with the creation of sysfs
files for USB devices. Turns out that there are now userspace tools
out there that are hitting this long-known bug, so it's time to fix
them. Thankfully the tool-maker in this case fixed the issue :)
The other patches in here are all fixes for reported issues. Now that
syzbot knows how to fuzz USB drivers better, and is starting to now
fuzz the userspace facing side of them at the same time, there will be
more and more small fixes like these coming, which is a good thing.

The simplest way to fix is to revert commit 89e0341af082 ("bcache: use
sysfs_match_string() instead of __sysfs_match_string()").
This bug was introduced in Linux v5.2, so this fix only applies to
Linux v5.2 is enough for stable tree maintainer.

In order to implement clock switching for the CLKID_CPU_CLK and
CLKID_CPUB_CLK, notifiers are added on specific points of the
clock tree :
cpu_clk / cpub_clk
| \- cpu_clk_dyn
| | \- cpu_clk_premux0
| | |- cpu_clk_postmux0
| | | |- cpu_clk_dyn0_div
| | | \- xtal/fclk_div2/fclk_div3
| | \- xtal/fclk_div2/fclk_div3
| \- cpu_clk_premux1
| |- cpu_clk_postmux1
| | |- cpu_clk_dyn1_div
| | \- xtal/fclk_div2/fclk_div3
| \- xtal/fclk_div2/fclk_div3
\ sys_pll / sys1_pll
This for each cluster, a single one for G12A, two for G12B.
Each cpu_clk_premux1 tree is marked as read-only and CLK_SET_RATE_NO_REPARENT,
to be used as "parking" clock in a safe clock frequency.
A notifier is added on each cpu_clk_premux0 to detech when CCF want to
change the frequency of the cpu_clk_dyn tree.
In this notifier, the cpu_clk_premux1 tree is configured to use the xtal
clock and then the cpu_clk_dyn is switch to cpu_clk_premux1 while CCF
updates the cpu_clk_premux0 tree.
A notifier is added on each sys_pll/sys1_pll to detect when CCF wants to
change the PLL clock source of the cpu_clk.
In this notifier, the cpu_clk is switched to cpu_clk_dyn while CCF
updates the sys_pll/sys1_pll frequency.
A third small notifier is added on each cpu_clk / cpub_clk and cpu_clk_dyn,
add a small delay at PRE_RATE_CHANGE/POST_RATE_CHANGE to let the other
notofiers change propagate before changing the cpu_clk_premux0 and sys_pll
clock trees.
This notifier set permits switching the cpu_clk / cpub_clk without any
glitches and using a safe parking clock while switching between sub-GHz
clocks using the cpu_clk_dyn tree.
This setup has been tested and validated on the Amlogic G12A and G12B
SoCs running the arm64 cpuburn at [1] and cycling between all the possible
cpufreq translations of each cluster and checking the final frequency using
the clock-measurer, script at [2].

Add a clock driver for the cpu dynamic divider, this divider needs
to have a flag set before setting the divider value then removed
while writing the new value to the register.
This drivers implements this behavior and will be used essentially
on the Amlogic G12A and G12B SoCs for cpu clock trees.

Introduce the clk_hw_set_parent() provider call to change parent of
a clock by using the clk_hw pointers.
This eases the clock reparenting from clock rate notifiers and
implementing DVFS with simpler code avoiding the boilerplates
functions as __clk_lookup(clk_hw_get_name()) then clk_set_parent().

A deadlock with this stacktrace was observed.
The loop thread does a GFP_KERNEL allocation, it calls into dm-bufio
shrinker and the shrinker depends on I/O completion in the dm-bufio
subsystem.
In order to fix the deadlock (and other similar ones), we set the flag
PF_MEMALLOC_NOIO at loop thread entry.

Currently, the authorized_default and interface_authorized_default
attributes for HCD are set up after the uevent has been sent to userland.
This creates a race condition where userland may fail to access this
file when processing the event. Move the appending of these attributes
earlier relying on the usb_bus_notify dispatcher.

Commit 4a6ef8e37c4d ("pwm: Add support referencing PWMs from ACPI")
made pwm_get unconditionally return the acpi_pwm_get return value if
the device passed to pwm_get has an ACPI fwnode.
But even if the passed in device has an ACPI fwnode, it does not
necessarily have the necessary ACPI package defining its pwm bindings,
especially since the binding / API of this ACPI package has only been
introduced very recently.
Up until now X86/ACPI devices which use a separate pwm controller for
controlling their LCD screen's backlight brightness have been relying
on the static lookup-list to get their pwm.
pwm_get unconditionally returning the acpi_pwm_get return value breaks
this, breaking backlight control on these devices.
This commit fixes this by making pwm_get fall back to the static
lookup-list if acpi_pwm_get returns -ENOENT.

We have to drop the mutex before we close() upon disconnect()
as close() needs the lock. This is safe to do by dropping the
mutex as intfdata is already set to NULL, so open() will fail.
