wfx_tx_queues_clear() only clear not yet sent requests. So, it always
necessary to wait for tx_queue_stats.wait_link_id_empty whatever the
value of "drop" argument.
In add, it is not necessary to return with tx queue locked since all
calls to __wfx_flush() unlock the tx queue just after the call to
__wfx_tx_flush().

mac80211 and the device are both able to control tx power per vif. But,
the current code retrieve tx power from wfx_config(). So, it does not
allow to setup the tx power independently for each vif. Driver just has
to rely on bss_conf->txpower to get the correct information.
In add, it is no more necessary to protect access to wdev->output_power
with scan_lock.

Most of the commands that are sent to device should take struct in

Rate policies (aka. tx_rate_retry_policy in hardware API) are sent to
device asynchronously from tx requests. So, the device maintains a list
of active rate policies and the tx requests only reference an existent
rate policy.
The device API allows to send multiple rate policies at once. However,
this property is very rarely used. We prefer to send rate policies one
by one and simplify the architecture.

Pull thread fixes from Christian Brauner:
"This contains a series of patches to fix CLONE_SETTLS when used with
clone3().
The clone3() syscall passes the tls argument through struct clone_args
instead of a register. This means, all architectures that do not
implement copy_thread_tls() but still support CLONE_SETTLS via
copy_thread() expecting the tls to be located in a register argument
based on clone() are currently unfortunately broken. Their tls value
will be garbage.
The patch series fixes this on all architectures that currently define
__ARCH_WANT_SYS_CLONE3. It also adds a compile-time check to ensure
that any architecture that enables clone3() in the future is forced to
also implement copy_thread_tls().
My ultimate goal is to get rid of the copy_thread()/copy_thread_tls()
split and just have copy_thread_tls() at some point in the not too
distant future (Maybe even renaming copy_thread_tls() back to simply
copy_thread() once the old function is ripped from all arches). This
is dependent now on all arches supporting clone3().
While all relevant arches do that now there are still four missing:
ia64, m68k, sh and sparc. They have the system call reserved, but not
implemented. Once they all implement clone3() we can get rid of
ARCH_WANT_SYS_CLONE3 and HAVE_COPY_THREAD_TLS.
This series also includes a minor fix for the arm64 uapi headers which
caused __NR_clone3 to be missing from the exported user headers.
Unfortunately the series came in a little late especially given that
it touches a range of architectures. Due to the holidays not all arch
maintainers responded in time probably due to their backlog. Will and
Arnd have thankfully acked the arm specific changes.
Given that the changes are straightforward and rather minimal combined
with the fact the that clone3() with CLONE_SETTLS is broken I decided
to send them post rc3 nonetheless"

Here's that one patch, it's been in linux-next for a while with no
reported issues and it does fix the reported problem"

Here are some small staging driver fixes for 5.5-rc6.
Nothing major here, just some small fixes for a comedi driver, the
vt6656 driver, and a new device id for the rtl8188eu driver.
All of these have been in linux-next for a while with no reported
issues.

Here are two tty/serial driver fixes for 5.5-rc6.
The first fixes a much much reported issue with a previous tty port link
patch that is in your tree, and the second fixes a problem where the
serdev driver would claim ACPI devices that it shouldn't be claiming.
Both have been in linux-next for a while with no reported issues.
