b8c8a03e9b wifi: iwlwifi: mvm: fix PNVM timeout for non-MSI-X platforms 
When MSI-X is not enabled, we mask all the interrupts in the interrupt
handler and re-enable them when the interrupt thread runs. If
STATUS_INT_ENABLED is not set, we won't re-enable in the thread.
In order to get the ALIVE interrupt, we allow the ALIVE interrupt
itself, and RX as well in order to receive the ALIVE notification (which
is received as an RX from the firmware.

The problem is that STATUS_INT_ENABLED is clear until the op_mode calls
trans_fw_alive which means that until trans_fw_alive is called, any
notification from the firmware will not be received.

This became a problem when we inserted the pnvm_load exactly between the
ALIVE and trans_fw_alive.

Fix that by calling trans_fw_alive before loading the PNVM. This will
allow to get the notification from the firmware about PNVM load being
complete and continue the flow normally.

This didn't happen on MSI-X because we don't disable the interrupts in
the ISR when MSI-X is available.

The error in the log looks like this:

iwlwifi 0000:00:03.0: Timeout waiting for PNVM load!
iwlwifi 0000:00:03.0: Failed to start RT ucode: -110
iwlwifi 0000:00:03.0: WRT: Collecting data: ini trigger 13 fired (delay=0ms).

f9751163bf wifi: iwlwifi: mvm: clean up ROC on failure 
If the firmware fails to start the session protection, then we
do call iwl_mvm_roc_finished() here, but that won't do anything
at all because IWL_MVM_STATUS_ROC_P2P_RUNNING was never set.
Set IWL_MVM_STATUS_ROC_P2P_RUNNING in the failure/stop path.
If it started successfully before, it's already set, so that
doesn't matter, and if it didn't start it needs to be set to
clean up.

Not doing so will lead to a WARN_ON() later on a fresh remain-
on-channel, since the link is already active when activated as
it was never deactivated.

9eca1abfb4 wifi: iwlwifi: mvm: improve/fix chanctx min_def use logic 
There are two cases in which the min_def isn't used:
 a) if FILS will be enabled
 b) if FTM responder is enabled

Both of these apply to AP mode only, but for FILS we're
not checking that right now. Change the code to iterate
the interfaces and links using the channel context, and
check for AP mode for both, not just for FTM responder.

In the case of iwl_mvm_enable_fils() this might also fix
an issue where FILS is enabled for an IBSS network that
happens to be started on 6 GHz, though that's not very
likely to be possible due to regulatory.

However for RX OMI bandwidth reduction the driver needs
to use the min_def in client mode as well, in order to
actually reduce bandwidth when it requested that.

9673c35486 wifi: iwlwifi: implement product reset for TOP errors 
The TOP is a shared (between BT and WiFi) hardware component,
and if it has an error we need to reset the whole device, i.e.
both BT and WiFi. This is achieved by calling a specific ACPI
DSM (device-specific method) with the right arguments before
doing a reset via the object referenced by _PRR.

Since this is needed here, but a function reset will always do
better than just re-enumerating the bus in case of errors, we
can always try to at least do a function reset and do the full
product reset only when needed for TOP errors.

Also, for some Bz and Sc devices where BT is PCIe/IOSF as well,
find the BT device and unbind that device as well so the BT
driver can recover from the reset that's going to happen,
rather than having to somehow detect that the device was reset.

Also add - currently unused - the function reset mode, this is
going to get used in the upcoming escalation model.

79f4b6934d wifi: iwlwifi: mvm: remove unneeded NULL pointer checks 
Smatch reported that we dereference the data pointer to calculate the
expected length before we check it's not NULL. While this is true (and
hence needs to be fixed), this will never happen because the data
pointer comes from struct iwl_rx_packet object which has the following
layout:

struct iwl_rx_packet {
        __le32 len_n_flags;
        struct iwl_cmd_header hdr;
        u8 data[];
} __packed;

So, if the pointer to iwl_rx_packet is valid, data will be valid as
well.

Remove the NULL pointer check on 'data' to avoid confusing smatch.
Also remove the check from similar functions in the same flow that were
cargo cult copy-pasted.

c866a98523 wifi: iwlwifi: mvm: fix add stream vs. restart race 
My recent restart related work has made this race more likely
to happen and we've now noticed it, but it seems that it was
always possible. The race is that the add stream work can be
scheduled just before a restart is scheduled and then execute
before the restart, accessing the device while it's doing the
restart and not accessible.

To fix this, check if the device is restarting and abort the
work in that case. Reschedule it after the restart as well.
