78f7aeb08f ath10k: Enable AP + STA interface combination support for 10.x
Enable AP + STA interface combination support for 10.x and
this enables Repeater mode testing (with WDS Repeater combinations
as well). Fix indentation as well.

Based on the suggestions from Michal and Yanbo Li,
thanks to them

952348a5f8 rt2x00: type bug in _rt2500usb_register_read()
This code causes a static checker bug.

drivers/net/wireless/ralink/rt2x00/rt2500usb.c:232 _rt2500usb_register_read()
warn: passing casted pointer 'value' to 'rt2500usb_register_read()' 32 vs 16.

If the low 16 bits were initialized to zero then this code would only be
a problem on big endian systems.  But in this case this is case the low
16 bits are never initialized.  This is called from a function which is
created using a macro:

RT2X00DEBUGFS_OPS(csr, "0x%.8x\n", u32);

We end up copying uninitialized data to the user which is bogus and an
information leak.

6a23863eaa brcmfmac: Change error print on wlan0 existence.
During initialization of the device, but also on some other
moments the driver prints an error that the netdev already exists.
This is a result of the way the driver is initializing the
firmware and not really an error. The code is not treating it as
an error either. This error print has resulted in many questions
by users and is confusing and incorrect. This patch changes the
error log into a debug info log.

Over time, use cases become more and more complex, with multiple

This, in turn, requires us to elaborate our prioritization mechanism.
However, our legacy products included hw that does not supports this,

The kfree_skb() function tests whether its argument is NULL and then
returns immediately. Thus the test around the calls is not needed.

This issue was detected by using the Coccinelle software.

The brcmf_bus_ops structures are never modified, so declare them as const.

Done with the help of Coccinelle.

3a318426e0 ath9k_htc: check for underflow in ath9k_htc_rx_msg()
We check for overflow here, but we don't check for underflow so it
causes a static checker warning.

Fixes: fb9987d0f7 ('ath9k_htc: Support for AR9271 chipset.')
