rndis_wlan.c:3147:25: warning: Assigned value is garbage or undefined
wiphy->max_num_pmkids = le32_to_cpu(caps.num_pmkids);
^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The setting of caps happens here, with a call to rndis_query_oid()
retval = rndis_query_oid(usbdev,
if (retval >= 0) {
Reviewing rndis_query_oid() shows that on success 0 is returned,
failure is otherwise. So the retval check is not tight enough.
So tighten the retval check. Similar problem in
rndis_wlan_get_caps().

A possible call chain is as follow:
mwifiex_sdio_interrupt (sdio.c)
--> mwifiex_main_process (main.c)
--> mwifiex_process_cmdresp (cmdevt.c)
--> mwifiex_process_sta_cmdresp (sta_cmdresp.c)
--> mwifiex_ret_802_11_scan (scan.c)
--> mwifiex_parse_single_response_buf (scan.c)
'mwifiex_sdio_interrupt()' is an interrupt function.
Also note that 'mwifiex_ret_802_11_scan()' already uses GFP_ATOMIC.
So use GFP_ATOMIC instead of GFP_KERNEL when memory is allocated in
'mwifiex_parse_single_response_buf()'.

As a part of device shutdown the smmu driver will be
stopped and henceforth any IOVA address translation
will not be done. The wlan driver, being one of the
smmu driver consumer, should stop all the dma related
activity as a part of shutdown, and thereby ensuring
that no dma activity is done once the smmu driver
shuts down.
During the device shutdown, the smmu calls shutdown
for all its consumers in order to indicate them to
stop all their dma activities.
Register the shutdown handler to stop the wlan
driver and avoid any dma operations.

For QCA6390, normal power up and power down can't bring MHI
to a workable state. This happens especially in warm reboot
and rmmod and insmod. Host needs to write a few registers to
bring MHI to normal state.

For QCA6390, only one pdev is created and this pdev manages both lmacs, thus
both rxdmas. So host needs to initialize all rxdma related rings for one pdev.
Another difference is for QCA6390, host fills rxbuf to firmware and firmware
further fills the rxbuf to rxbuf ring for each rxdma.

For QCA6390, it has 2 lmacs and thus 2 rxdmas. However, each rxdma has rxdma0
only, and doesn't have rxdma1. So for QCA6390, don't initialize rxdma1 related
rings such as rx_mon_buf_ring, rx_mon_dst_ring and rx_mon_desc_ring.

For QCA6390, host puts hardware to Dual Band Simultaneous (DBS) mode by default
so both 2G and 5G bands can be used. Otherwise only the 5G band can be used.
QCA6390 doesn't provide band_to_mac configuration and firmware will do the
band_to_mac map.

There's no reason to have call for enable_pll_clk in ath10k_bmi_start(), move
it to ath10k_core_start() instead. This way it's possible to call

function call is more visible when it's in core.c.

The value of "htc_hdr->endpoint_id" comes from skb->data so Smatch marks
it as untrusted so we have to check it before using it as an array
offset.
This is similar to a bug that syzkaller found in commit e4ff08a4d7
("ath9k: Fix use-after-free Write in ath9k_htc_rx_msg") so it is
probably a real issue.

The ath9k driver was so far only able to rekey PTK0 keys correctly due
to the best effort queue flush added with commit 62872a9b9a
("mac80211: Fix PTK rekey freezes and clear text leak").
Add the needed queue flush and set NL80211_EXT_FEATURE_CAN_REPLACE_PTK0
to tell mac80211 that the driver can now rekey PTK0 keys correctly and
no longer needs the best effort flush.
Effectively this prevents mac80211 to warn when rekeying a PTK0 key
only.
