[ Upstream commit 8a59d39033c35bb484f6bd91891db86ebe07fdc2 ]

The RX handlers for probe response data and channel switch weren't
hooked up properly, fix that.

Should an error occur after calling 'ath10k_usb_create()', it should be

ath10k: Fix the parsing error in service available event

2020-12-30T10:51:15+00:00

[ Upstream commit c7cee9c0f499f27ec6de06bea664b61320534768 ]

The wmi service available event has been
extended to contain extra 128 bit for new services
to be indicated by firmware.

Currently the presence of any optional TLVs in
the wmi service available event leads to a parsing
error with the below error message:
ath10k_snoc 18800000.wifi: failed to parse svc_avail tlv: -71

The wmi service available event parsing should
not return error for the newly added optional TLV.
Fix this parsing for service available event message.

orinoco: Move context allocation after processing the skb

[ Upstream commit a31eb615646a63370aa1da1053c45439c7653d83 ]

ezusb_xmit() allocates a context which is leaked if
orinoco_process_xmit_skb() returns an error.

Move ezusb_alloc_ctx() after the invocation of
orinoco_process_xmit_skb() because the context is not needed so early.
ezusb_access_ltv() will cleanup the context in case of an error.

mwifiex: fix mwifiex_shutdown_sw() causing sw reset failure

2020-12-30T10:51:06+00:00

[ Upstream commit fa74cb1dc0f4da46c441b735ca865ac52de42c0e ]

When a PCIe function level reset (FLR) is performed but without fw reset for
some reasons (e.g., on Microsoft Surface devices, fw reset requires other
quirks), it fails to reset wifi properly. You can trigger the issue on such
devices via debugfs entry for reset:

    $ echo 1 | sudo tee /sys/kernel/debug/mwifiex/mlan0/reset

and the resulting dmesg log:
