This will add usb_alloc_noncoherent() and usb_free_noncoherent()
functions to support alloc and free buffer in a dma-noncoherent way.
To explicit manage the memory ownership for the kernel and device,
this will also add usb_dma_noncoherent_sync_for_cpu/device() functions
and call it at proper time. The management requires the user save
sg_table returned by usb_alloc_noncoherent() to urb->sgt.

When writing an empty string to either 'qw_sign' or 'landingPage'
sysfs attributes, the store functions attempt to access page[l - 1]
before validating that the length 'l' is greater than zero.
This patch fixes the vulnerability by adding a check at the beginning
of os_desc_qw_sign_store() and webusb_landingPage_store() to handle
the zero-length input case gracefully by returning immediately.

When SAE commit is sent and received in response, there's no
ordering for the SAE confirm messages. As such, don't call
drivers to stop listening on the channel when the confirm
message is still expected.
This fixes an issue if the local confirm is transmitted later
than the AP's confirm, for iwlwifi (and possibly mt76) the
AP's confirm would then get lost since the device isn't on
the channel at the time the AP transmit the confirm.
For iwlwifi at least, this also improves the overall timing
of the authentication handshake (by about 15ms according to
the report), likely since the session protection won't be
aborted and rescheduled.
Note that even before this, mgd_complete_tx() wasn't always
called for each call to mgd_prepare_tx() (e.g. in the case
of WEP key shared authentication), and the current drivers
that have the complete callback don't seem to mind. Document
this as well though.

Implement dot11ExtendedRegInfoSupport to advertise non-AP station
regulatory power capability as part of regulatory connectivity
element in (Re)Association request frames so that AP can achieve
maximum client connectivity. Control field which was interpreted
using value of 3-bits B5 to B3, now uses value of 4-bits B6 to B3 to
interpret the type of AP. Hence update IEEE80211_HE_6GHZ_OPER_CTRL_REG_INFO
to parse 4-bits control field. If older AP still updates only 3-bits
value of control field, station can still interpret the value as per
section E.2.7 of IEEE 802.11 REVme D7.0 and support the appropriate
AP type.
Also update IEEE80211_6GHZ_CTRL_REG_INDOOR_SP_AP as the value of
standard power AP is changed to 8 instead of 4 so that AP can support both
LPI AP and SP AP to maximize the connectivity with stations. For backward
compatibility, keeping value 4 as old AP by limiting it to SP AP only.

Currently the code only sends extended MLD capa/ops in
strict mode, but if the AP has it then it should also
be able to parse it. There could be cases where the AP
doesn't have it but we would want to advertise it (e.g.
if the AP supports nothing but we want to have BTM.),
but given the broken deployed APs out there right now
this is the best we can do.

If we get to the error path of ieee80211_prep_connection, for example
because of a FW issue, then ieee80211_vif_set_links is called
with 0.
But the call to drv_change_vif_links from ieee80211_vif_update_links
will probably fail as well, for the same reason.
In this case, the valid_links and active_links bitmaps will be reverted
to the value of the failing connection.
Then, in the next connection, due to the logic of
ieee80211_set_vif_links_bitmaps, valid_links will be set to the ID of
the new connection assoc link, but the active_links will remain with the
ID of the old connection's assoc link.
If those IDs are different, we get into a weird state of valid_links and
active_links being different. One of the consequences of this state is
to call drv_change_vif_links with new_links as 0, since the & operation
between the bitmaps will be 0.
Since a removal of a link should always succeed, ignore the return value
of drv_change_vif_links if it was called to only remove links, which is
the case for the ieee80211_prep_connection's error path.
That way, the bitmaps will not be reverted to have the value from the
failing connection and will have 0, so the next connection will have a
good state.

Runtime PM updates related to autosuspend for 6.17
Make several autosuspend functions mark last busy stamp and update
the documentation accordingly (Sakari Ailus).
Some device names were wrong because our internal data suggested
that discrete Ga devices have B-step RF, when they actually have
C-step. However, matching the step for them is bad anyway.
Change the code to be able to find the devinfo depending on the
device being integrated or discrete. This is only for the names,
since the RF config cannot be different for the same RF because
it's discrete or integrated, so add a kunit test that ensures
both (a) the RF config is the same and (b) the name is different
(the latter really only because that's the whole point of having
a match on the discrete/integrated bit.)
Remove the RF step matching since it's no longer needed now.

size_t is 'unsigned long' for 64-bit platforms but 'unsigned int' for
32-bit platforms, so '%ld' is not correct. Use the proper size_t
specifier, '%zu', to resolve the warnings on 32-bit platforms while not
affecting 64-bit platforms.

Fix the smatch warning,
smatch warnings:
drivers/gpu/drm/amd/amdgpu/amdgpu_debugfs.c:2146 amdgpu_pt_info_read()
error: we previously assumed 'fpriv' could be null (see line 2146)
"if (!fpriv && !fpriv->vm.root.bo)", It has to be an OR condition
rather than an AND which makes an NULL dereference in case fpriv is NULL.

This requires four changes:
* Using the cpufreq-dt register helper to establish a hard dependency
for depmod to track
* Adding a remove routine to remove the cpufreq-dt device
* Adding a exit routine to handle cleaning up the driver
* Populating module license

Cpufreq-dt currently exports no functions. This means that drivers that
are based on cpufreq-dt have no way of establishing a depmod dependency
on it. This helper allows that link.
