In MCC_UPDATE_CMD we get from the FW the number of entries in the
channel info array. We used to WARN_ON if this parameter is greater
than we expected. Since this is not really a driver bug, and since it
might happen in some valid cases too, we shouldn't use a warning here.
Fix this by replacing the WARN_ON with a debug print.

Due to preg protection we cannot write to this register
while FW is running (when FW in Halt it is ok).
since we have some cases that we need to dump this
region while FW is running remove this writing from DRV.
FW will do this writing.

Since commit a05829a7222e ("cfg80211: avoid holding the RTNL when
calling the driver") we're not only holding the RTNL when going
in and out of suspend, but also the wiphy->mtx. Add that to the
D3 test debugfs in iwlwifi since it's required for various calls
to mac80211.

We may not have all the interfaces added to the driver when we get the
THERMAL_DUAL_CHAIN_REQUEST notification from the FW, so instead of
iterating all vifs to update SMPS, iterate only the ones that are
already assigned. The interfaces that were not assigned yet, will be
updated accordingly when we start using them.

Until now function just got a pointer to some buffer and used it as if
it's good to use with no boundaries about size left in the buffer.
This infra helps for internal functions ops to make sure buffer usage
is in bound of allocation.
We also add external checks with warnings to verify every internal
function didn't exceed usage of the free buffer size.

Most of this change is a continuation of commit 403ea939ea6a
("iwlwifi: dbg: Mark ucode tlv data as const") propagating the
(const) type qualifier for ucode based tlv data to avoid having
the impression that it is writeable.
The other part of the change preserves the (const) type qualifier
over casts and function calls where it was previously lost.
Both changes are needed to avoid compile time errors on system with
more strict error settings, in this case found with clang on FreeBSD.

In order to de-const variables simply casting through (void *) is
not enough: "cast from 'const .. *' to 'void *' drops const qualifier".
Cast through (uintptr_t) as well [1] to make this compile on systems
with more strict requirements.
In addition passing const void *data to dma_map_single() also
drops the (const) qualifier. De-constify on variable on assignment
which may be overwritten later. In either case the (void *) cast
to dma_map_single() is not needed (anymore) either.

The order of arguments for iwl_cmd_id() is confusing, and the
version is always 0 and thus a useless argument. Prefer the
WIDE_ID() macro (which needs to be a macro due to use in switch
cases etc.) over the iwl_cmd_id() function.
Obviously done with spatch:

expression G, C;

-iwl_cmd_id(C, G, 0)

Since FW is now in charge of timing the channel switch, there is no need
to send the add/modify/remove time event command to fw with every (e)CSA
element.
However, the driver needs to cancel the channel switch if the CS start
notification arrives and it does not know about an ongoing channel switch.

The recent fix for NULL sta in iwl_mvm_get_tx_rate() still has a call
of iwl_mvm_sta_from_mac80211() that may be called with NULL sta.
Although this practically only points to the address and the actual
access doesn't happen due to the conditional evaluation at a later
point, it looks a bit flaky.
This patch drops the temporary variable above and evaluates
iwm_mvm_sta_from_mac80211() directly for avoiding confusions.
