Subject: [PATCH 00/12] iwlwifi: updates intended for v5.13 2021-04-11

From: Luca Coelho <[email protected]>

Hi,

Here's the third set of patches intended for v5.13. It's the usual
development, new features, cleanups and bugfixes.

The changes are:

* Support for a new FW API command version;
* Some locking fixes;
* Some other small fixes, clean-ups and improvements.

As usual, I'm pushing this to a pending branch, for kbuild bot, and
will send a pull-request later.

Please review.

Cheers,
Luca.

Subject: [PATCH 03/12] iwlwifi: don't warn if we can't wait for empty tx queues

From: Emmanuel Grumbach <[email protected]>

If the firmware is dead, the Tx queues won't drain, but
leaving a print in the log is enough, no need to WARN.
If the firmware is dead, we must already have printed enough
information in the log anyway.

Subject: [PATCH 04/12] iwlwifi: queue: avoid memory leak in reset flow

From: Mordechay Goodstein <[email protected]>

In case the device is stopped any usage of hw queues needs to be
reallocated in fw due to fw reset after device stop, so all driver
internal queue should also be freed, and if we don't free the next usage
would leak the old memory and get in recover flows
"iwlwifi 0000:00:03.0: dma_pool_destroy iwlwifi:bc" warning.

Also warn about trying to reuse an internal allocated queue.

Subject: [PATCH 08/12] iwlwifi: pcie: merge napi_poll_msix functions

From: Mordechay Goodstein <[email protected]>

The only difference between iwl_pcie_napi_poll_msix_shared() and
iwl_pcie_napi_poll_msix() is when we have a shared queue and nothing
in the rx queue. This case doesn't affect CPU performance, so we can
merge the two functions.

From: Johannes Berg <[email protected]>

We cannot lock a mutex while we're in an RCU critical section. At
the same time, we're accessing data structures that are protected
by the mvm->mutex anyway, so just move the entire locking here to
use only that.
