Here is the "big" set of staging and IIO driver patches for 5.12-rc1.
Nothing really huge in here, the number of staging tree patches has gone
down for a bit, maybe there's only so much churn to happen in here at
the moment.
The IIO changes are:
- new drivers
- new DT bindings
- new iio driver features
with full details in the shortlog.
The staging driver patches are just a lot of tiny coding style cleanups,
along with some semi-larger hikey driver cleanups as those are _almost_
good enough to get out of the staging tree, but will probably have to
wait until 5.13 to have happen.
All of these have been in linux-next with no reported issues.

There is a regular need in the kernel to provide a way to declare having
a dynamically sized set of trailing elements in a structure. Kernel code
should always use “flexible array members”[1] for these cases. The older
style of one-element or zero-length arrays should no longer be used[2].
Refactor the code according to the use of a flexible-array member in
struct ndis_80211_var_ie, instead of a one-element array.
Also, this helps with the ongoing efforts to enable -Warray-bounds and
fix the following warnings:

Commit 81f153faac ("staging: rtl8723bs: fix wireless regulatory API
misuse") moved the wiphy_apply_custom_regulatory() call to earlier in the
driver's init-sequence, so that it gets called before wiphy_register().
But at this point in time the eFuses which code the regulatory-settings
for the chip have not been read by the driver yet, causing
_rtw_reg_apply_flags() to set the IEEE80211_CHAN_DISABLED flag on *all*
channels.
On the device where I initially tested the fix, a Jumper EZpad 7 tablet,
this does not cause any problems because shortly after init the
rtw_reg_notifier() gets called fixing things up. I guess this happens
into response to receiving a (broadcast) packet with regulatory info
from the access-point ?
But on another device with a RTL8723BS wifi chip, an Acer Switch 10E
(SW3-016), the rtw_reg_notifier() never gets called. I assume that some
fuse has been set on this device to ignore regulatory info received from
access-points.
This means that on the Acer the driver is stuck in a state with all
channels disabled, leading to non working Wifi.
We cannot move the wiphy_apply_custom_regulatory() call back, because
that call must be made before the wiphy_register() call.
Instead move the entire rtw_wdev_alloc() call to after the Efuses have
been read, fixing all channels being disabled in the initial channel-map.

This code ends up calling wiphy_apply_custom_regulatory(), for which
we document that it should be called before wiphy_register(). This
driver doesn't do that, but calls it from ndo_open() with the RTNL
held, which caused deadlocks.
Since the driver just registers static regdomain data and then the
notifier applies the channel changes if any, there's no reason for
it to call this in ndo_open(), move it earlier to fix the deadlock.
