The driver attempts to clear persistence bit on any device familiy even
though only 9000 and 22000 families require it. Clear the bit only on
the relevant device families.
Each HW has different address to the write protection register. Use the
right register for each HW

When we have a single image (same firmware image for INIT and
OPERATIONAL), we couldn't load the driver and register to the
stack if we had hardware RF-Kill asserted.
Fix this. This required a few changes:
1) Run the firmware as part of the INIT phase even if its
ucode_type is not IWL_UCODE_INIT.
2) Send the commands that are sent to the unified image in
INIT flow even in RF-Kill.
3) Don't ask the transport to stop the hardware upon RF-Kill
interrupt if the RF-Kill is asserted.
4) Allow the RF-Kill interrupt to take us out of L1A so that
the RF-Kill interrupt will be received by the host (to
enable the radio).

This debugfs file is really old, and cannot work properly since
the unified image support. Rather than trying to make it work,
which is difficult now due to multiple images (LMAC/UMAC etc.)
just remove it - we no longer need it since we properly do a FW
coredump even in D3 cases.

Currently mwifiex_update_bss_desc_with_ie() implicitly assumes that

In b43_request_firmware(), when ieee80211_register_hw() fails,
b43_one_core_detach() is called. In b43_bcma_remove() and
b43_ssb_remove(), b43_one_core_detach() is called again. In this case,
null-pointer dereferences and double-free problems can occur when
the driver is removed.
To fix this bug, the call to b43_one_core_detach() in
b43_request_firmware() is deleted.

In this step, the read/write routines for the descriptors are converted
to use __le32 quantities, thus a lot of casts can be removed. Callback
routines still use the 8-bit arrays, but these are changed within the
specified routine.
The macro that cleared a descriptor has now been converted into an inline
routine.

As a first step in the conversion, the macros that set the RX and TX
descriptors are converted to static inline routines, and the names are
changed from upper to lower case. To minimize the changes in a given
step, the input descriptor information is left as as a byte array
(u8 *), even though it should be a little-endian word array (__le32 *).
That will be changed later.

This driver uses a set of local macros to manipulate the RX and TX
descriptors, which are all little-endian quantities. These macros
are replaced by the bitfield macros le32p_replace_bits() and
le32_get_bits(). In several places, the macros operated on an entire
32-bit word. In these cases, a direct read or replacement is used.

ofdm_index_old[] is the index of ofdmswing_table[], and used to indicate
initial value of ROFDM0_X{A,B}TXIQIMBALANCE in rtl8192de_phy_reg_2tarray[]
table, and the initial value is corresponding to calibration thermal value
written in efuse, namely rtlefuse->eeprom_thermalmeter. Then, local
variable ofdm_index_old[] save to rtlpriv->dm.ofdm_index[] for operational
use.
If thermal value (temperature) is increasing, output TX power is lower.
So, we calculate the delta between current and calibration thermal value,
then add power to yield expected and the same output TX power.
Thus, ofdm_index[] should be initialized as rtlpriv->dm.ofdm_index[], and
shift to proper index depends on delta of thermal value. Then, new power
value ofdmswing_table[ofdm_index[]] is written to register.

This patch fixes an issue with wpa_supplicant dropping all scan
results because their where considered to be "too old" (e.g.:
"skip - scan result not recent enough (121056.086325 seconds too old)")
which is very weird because this looks like that the scan results have
been received before a scan started. This is due to the inaccuracy of
the default timing mechanism for calculating the BSS entry age.

This patch fixes a crash that got introduced when the
mentioned patch replaced the direct list_head access
with skb_peek_tail(). When the device is starting up,
there are no entries in the queue, so previously to
"Use skb_peek_tail() instead..." the target_skb would
end up as the tail and head pointer which then could
be used by __skb_queue_after to fill the empty queue.
With skb_peek_tail() in its place will instead just
return NULL which then causes a crash in the
__skb_queue_after().

Remove circular lock dependency by using atomic version of interfaces
iterate in watch_dog_work(), hence avoid taking local->iflist_mtx

When building with -Wuninitialized, Clang warns:
drivers/net/wireless/rsi/rsi_91x_sdio.c:940:43: warning: variable 'data'
is uninitialized when used here [-Wuninitialized]
put_unaligned_le32(TA_HOLD_THREAD_VALUE, data);

drivers/net/wireless/rsi/rsi_91x_sdio.c:930:10: note: initialize the
variable 'data' to silence this warning
u8 *data;
^
= NULL
1 warning generated.
Using Clang's suggestion of initializing data to NULL wouldn't work out
because data will be dereferenced by put_unaligned_le32. Use kzalloc to
properly initialize data, which matches a couple of other places in this
driver.

The new rssi_level should be stored in si, otherwise the rssi_level will
never be updated and get a wrong RA mask, which is calculated by the
rssi level
If a wrong RA mask is chosen, the firmware will pick some *bad rates*.
The most hurtful scene will be in *noisy environment*, such as office or
public area with many APs and users.
The latency would be high and the overall throughput would be only half
or less.
Tested in 2.4G in office area, with this patch the throughput increased
from such as "1x Mbps -> 4x Mbps".
