In commit 33511b157b ("rtlwifi: add support to

patch works correctly for rtl8192cu, but there is a possibility of getting
the following warnings in the PCI drivers:

The warning is followed by a NULL pointer dereference as follows:

This problem was reported at http://thread.gmane.org/gmane.linux.kernel.wireless.general/138645,
but no solution was found at that time.
The problem was also reported at https://bugzilla.kernel.org/show_bug.cgi?id=9744
and this solution was developed and tested there.
The USB driver works with a NULL final argument in the adapter_tx() callback;
however, the PCI drivers need a struct rtl_tcb_desc in that position.

Fixes commit eae79b4f3e ("rsi: fix memory leak in rsi_load_ta_instructions()")
which stopped the driver from functioning.
Firmware data has been allocated using vmalloc(), resulting in memory
that cannot be used for DMA. Hence the firmware was first copied to a
buffer allocated with kmalloc() in the original code. This patch reverts
the commit and only calls "kfree()" to release the buffer after sending
the data. This fixes the memory leak without breaking the driver.
Add a comment to the kmemdup() calls to explain why this is done, and abort
if memory allocation fails.
Tested on a Topic Miami-Florida board which contains the rsi SDIO chip.
Also added the same kfree() call to the USB glue driver. This was not
tested on actual hardware though, as I only have the SDIO version.

* a fix for the stuck TFD queue mechanism - it was producing
noisy false alarms.
* a fix for the NIC prepare flow that prevented the driver
from being able to access the device on certain systems.
* a fix for the scan prority handling which allows the
regular scan to run even if a scheduled scan is already
running.
The stuck queue detection mechanism allows to detect queues
that are stuck. For sleeping clients, a queue may rightfully
be stuck: if a poor client implementation stays asleep for
more than 10s, then we don't want to trigger recovery flows
because of that client.
In order to cope with this, I added a mechanism that
monitors the state of the client: when a client goes to
sleep, the timer of his queues is frozen. When he wakes up,
the timer is reset to the right value so that if a client
was awake for more than 10s and the queues are stuck, only
then, the recovery flow will kick in.
This is valid only on non-shared queues: A-MPDU queues.
There was a bug in case we Tx to a sleeping client that has
an empty A-MPDU queue: the timer was armed to now + 10s.
This is bad, but pretty harmless.
The problem is that when the client wakes up, the timer is
modified to be now + remainder. But remainder is 0 since the
queue was empty when that client went to sleep...
Fix this by checking the state of the client before playing
with the timer when we add a packet to an empty queue.

The code checks the total number of iterations to differentiate
between regular scan and scheduled scan. However, regular scan has
a total of one iteration, not zero. As a result, regular scan will
have lower priority than it should have, and in case scheduled
scan is already running when regular scan is requested, regular scan
will be delayed until scheduled scan is aborted.
Fix that by checking for total iterations number of one as an
identifier for regular scan.

need to disable link power management before we can

won't get notified that we are requesting the device which
will prevent us from acquire ownership.

A long time ago, ath9k had issues during reset where the DMA engine
would stay active and could potentially corrupt memory.
To debug those issues, the driver would print warnings whenever they
occur.
Nowadays, these issues are gone and the primary cause of these messages
is if the MAC is stuck during reset or busy processing a long
transmission. This is fairly harmless, yet these messages continue to
worry users.
To reduce the number of bogus bug reports, turn these messages into
debug messages and count their occurence in the "reset" debugfs file.
