b41f96ecb9 wifi: Switch back to struct platform_driver::remove()
After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/net/wireless to use
.remove(), with the eventual goal to drop struct
platform_driver::remove_new(). As .remove() and .remove_new() have the
same prototypes, conversion is done by just changing the structure
member name in the driver initializer.

En passant several whitespace changes are done to make indentation
consistent in the struct initializers.

2e19a3b590 wifi: brcmfmac: release 'root' node in all execution paths
The fixed patch introduced an additional condition to enter the scope
where the 'root' device_node is released (!settings->board_type,
currently 'err'), which avoid decrementing the refcount with a call to
of_node_put() if that second condition is not satisfied.

Move the call to of_node_put() to the point where 'root' is no longer
required to avoid leaking the resource if err is not zero.

d1a54ec21b wifi: iwlwifi: mvm: tell iwlmei when we finished suspending
Since we no longer shut down the device in suspend, we also no longer
call iwl_mvm_mei_device_state() and this is a problem because iwlmei
expects this to be called when it runs its own suspend sequence. It
checks mei->device_down in iwl_mei_remove() which is called upon
suspend.

Fix this by telling iwlmei when we're done accessing the device.
When we'll wake up, the device should be untouched if CSME didn't use it
during the suspend time. If CSME used it, we'll notice it through the
CSR_FUNC_SCRATCH register.

The channels array in the cfg80211_scan_request has a __counted_by
attribute attached to it, which points to the n_channels variable. This
attribute is used in bounds checking, and if it is not set before the
array is filled, then the bounds sanitizer will issue a warning or a
kernel panic if CONFIG_UBSAN_TRAP is set.

This patch sets the size of allocated memory as the initial value for
n_channels. It is updated with the actual number of added elements after
the array is filled.

b4ebb58cb9 wifi: cfg80211: Remove the Medium Synchronization Delay validity check
Currently, when the driver attempts to connect to an AP MLD with multiple
APs, the cfg80211_mlme_check_mlo_compat() function requires the Medium
Synchronization Delay values from different APs of the same AP MLD to be
equal, which may result in connection failures.

This is because when the driver receives a multi-link probe response from
an AP MLD with multiple APs, cfg80211 updates the Elements for each AP
based on the multi-link probe response. If the Medium Synchronization Delay
is set in the multi-link probe response, the Elements for each AP belonging
to the same AP MLD will have the Medium Synchronization Delay set
simultaneously. If non-multi-link probe responses are received from
different APs of the same MLD AP, cfg80211 will still update the Elements
based on the non-multi-link probe response. Since the non-multi-link probe
response does not set the Medium Synchronization Delay
(IEEE 802.11be-2024-35.3.4.4), if the Elements from a non-multi-link probe
response overwrite those from a multi-link probe response that has set the
Medium Synchronization Delay, the Medium Synchronization Delay values for
APs belonging to the same AP MLD will not be equal. This discrepancy causes
the cfg80211_mlme_check_mlo_compat() function to fail, leading to
connection failures. Commit ccb964b4ab
("wifi: cfg80211: validate MLO connections better") did not take this into
account.

To address this issue, remove this validity check.

5c1b544563 wifi: rtlwifi: Drastically reduce the attempts to read efuse in case of failures
Syzkaller reported a hung task with uevent_show() on stack trace. That
specific issue was addressed by another commit [0], but even with that
fix applied (for example, running v6.12-rc5) we face another type of hung
task that comes from the same reproducer [1]. By investigating that, we
could narrow it to the following path:

(a) Syzkaller emulates a Realtek USB WiFi adapter using raw-gadget and
dummy_hcd infrastructure.

(b) During the probe of rtl8192cu, the driver ends-up performing an efuse
read procedure (which is related to EEPROM load IIUC), and here lies the
issue: the function read_efuse() calls read_efuse_byte() many times, as
loop iterations depending on the efuse size (in our example, 512 in total).

This procedure for reading efuse bytes relies in a loop that performs an
I/O read up to *10k* times in case of failures. We measured the time of
the loop inside read_efuse_byte() alone, and in this reproducer (which
involves the dummy_hcd emulation layer), it takes 15 seconds each. As a
consequence, we have the driver stuck in its probe routine for big time,
exposing a stack trace like below if we attempt to reboot the system, for
example:

task:kworker/0:3 state:D stack:0 pid:662 tgid:662 ppid:2 flags:0x00004000

 [...]

We propose hereby to drastically reduce the attempts of doing the I/O
reads in case of failures, restricted to USB devices (given that
they're inherently slower than PCIe ones). By retrying up to 10 times
(instead of 10000), we got reponsiveness in the reproducer, while seems
reasonable to believe that there's no sane USB device implementation in
the field requiring this amount of retries at every I/O read in order
to properly work. Based on that assumption, it'd be good to have it
backported to stable but maybe not since driver implementation (the 10k
number comes from day 0), perhaps up to 6.x series makes sense.

0e3e8284f8 wifi: rtw88: Enable the new RTL8821AU/RTL8812AU drivers
These are older Wifi 5 chips. RTL8821AU is 1x1, with or without
Bluetooth. RTL8812AU is 2x2, without Bluetooth.

Beamforming is not implemented. It looks like these chips need a
different implementation than what is in bf.c.

Speed tests with RTL8821AU: 137 Mbps download, 144 Mbps upload.
Speed tests with RTL8812AU: 344 Mbps download, 387 Mbps upload.

Station mode and AP mode were tested.

Bluetooth coexistence works. I used my Bluetooth headphones for
several days, listening to music and watching videos. There is only
a problem with the wifi speeds with one router:

With ISP's HG6544C router:
Official driver: 3/5 Mbps.
rtw88: a bit more, but not steady at all. Not enough to watch a 1080p
Youtube video.

With my D-Link Eagle R32 router running Openwrt, on the same channel:
Official driver: 6/10 Mbps.
rtw88: download starts around 30, climbs to 50 / upload is 10 Mbps.
I can watch a 1080p Youtube video.

The music doesn't cut out during any speed tests.

I also tested transferring files to and from my phone. I don't have
other types of Bluetooth devices to test.
