When fixing the initialization race, we neglected to account for
the fact that debugfs is initialized in wiphy_register(), and
some debugfs things went missing (or rather were rerooted to the
global debugfs root).
Fix this by adding debugfs entries only after wiphy_register().
This requires some changes in the rate control code since it
currently adds debugfs at alloc time, which can no longer be
done after the reordering.

The function iwl_mvm_remove_inactive_tids() returns bool, so we
should just check "if (ret)", not "if (ret >= 0)" (which would
do nothing useful here). We obviously therefore cannot use the
return value of the function for the free_queue, we need to use
the queue (i) we're currently dealing with instead.

Due to some hardware issues, queue 31 isn't usable on devices that have
32 queues (7000, 8000, 9000 families), which is correctly reflected in
the configuration and TX queue initialization.
However, the firmware API and queue allocation code assumes that there
are 32 queues, and if something actually attempts to use #31 this leads
to a NULL-pointer dereference since it's not allocated.
Fix this by limiting to 31 in the IWL_MVM_DQA_MAX_DATA_QUEUE, and also
add some code to catch this earlier in the future, if the configuration
changes perhaps.

In the context info, we need to indicate the correct RB size
to the device so that it will not think we have 4k when we
only use 2k. This seems to not have caused any issues right
now, likely because the hardware no longer supports putting
multiple entries into a single RB, and practically all of
the entries should be smaller than 2k.
Nevertheless, it's a bug, and we must advertise the right
size to the device.
Note that right now we can only tell it 2k vs. 4k, so for
the cases where we have more, still use 4k. This needs to
be fixed by the firmware first.

The iwl_trans_pcie_dyn_txq_free() function only releases the frames
that may be left on the queue by calling iwl_pcie_gen2_txq_unmap(),
but doesn't actually free the DMA ring or byte-count tables for the
queue. This leads to pretty large memory leaks (at least before my
queue size improvements), in particular in monitor/sniffer mode on
channel hopping since this happens on every channel change.
This was also now more evident after the move to a DMA pool for the
byte count tables, showing messages such as

The rtw88 driver defines emtpy functions with multiple indirections

1342 | static int rtw_pci_suspend(struct device *dev)
Better simplify it to rely on the conditional reference in
SIMPLE_DEV_PM_OPS(), and mark the functions as __maybe_unused to avoid
warning about it.
I'm not sure if these are needed at all given that the functions
don't do anything, but they were only recently added.

Thus it seems that kasprintf() with "%.*s" format can not be used for
duplicating a string with arbitrary length. Replace it with kstrndup().
Note that later this string is limited to NL80211_WIPHY_NAME_MAXLEN == 64,
but the code is simpler this way.

Third set of patches for v5.7. Nothing really special this time,
business as usual.
When pulling this to net-next there's again a conflict in:
drivers/net/wireless/intel/iwlwifi/pcie/drv.c
To solve this drop these three lines from the conflict (the first hunk
from "HEAD") as the whole AX200 block was moved above in the same
file:
IWL_DEV_INFO(0x2723, 0x1653, iwl_ax200_cfg_cc, iwl_ax200_killer_1650w_name),
IWL_DEV_INFO(0x2723, 0x1654, iwl_ax200_cfg_cc, iwl_ax200_killer_1650x_name),
IWL_DEV_INFO(0x2723, IWL_CFG_ANY, iwl_ax200_cfg_cc, iwl_ax200_name),
And keep all the __IWL_DEV_INFO() entries (the second hunk). In other
words, take everything from wireless-drivers-next. When running 'git
diff' after the resolution the output should be empty.
Major changes:
brcmfmac
* add USB autosuspend support
ath11k
* handle RX fragments
* enable PN offload
* add support for HE BSS color
iwlwifi
* support new FW API version
* support for EDCA measurements

Some of the places using this want the newline, but not all,
so remove the newline from it and generate it in the debugfs
files where it's desired.
The effect of this is not printing double newlines in debug
log messages.

The FW changed the maximum number of scan offload profiles to 8 in new
APIs. Support it by changing the scan_offload_profile_cfg struct to be
more dynamic, so we can reuse most of the code and only change size of

A couple of SoCs, which can be recognized by PCI device IDs 0xA0F0 and
0x43F0, need a longer wait for the xtal to stabilize. To handle this,
add a new trans_cfg structure for Qu devices with a larger
xtal_latency value and apply them to the devices recognized by these
IDs. Also add a flag that allows us to inform the FW that the low
latency xtal should be used.

This new command is mostly backwards compatible, with the exception
that the device_type element was changed into a bitmask. The device
type bit remains the same (because we only had 0 and 1 anyway), but
when using v1 we can't set any other bits, because that would change
the integer.
Other than that, the struct remains the same and the driver can set
the device_type bit in both cases, but it can only set the low_latency
bit if VER_2 is used.

These values are selected based on the PCI device ID, so the decision
to use them can be made early. By moving them to the trans_cfg, we
avoid duplicating the large cfg structs for small pieces of
data (sometimes a single boolean). This will also allow us to make
more decisions based on, for instance, the SoC type in used.
The trans_cfg concept changes a bit, because previously it was used
only to boot the device before reading further characteristics and now
it also contains more data that is associated with the device ID.

Add a new region type that allows us to dump the PCI config space.
This is mostly the same as dumping a memory region, but reading from
the device's config space instead.
In order to make this generic and independent of the trans type, we
make a function called iwl_dump_ini_config_iter() that calls a new op
in the transport to read its config space.
