Remember that those pointers have been freed by setting them
to NULL. Otherwise, we'd keep rxq pointing to random memory
which would prevent us from trying to re-allocate the Rx
resources if we call rx_alloc again.
Also, propagate the allocation failure to the caller of
iwl_pcie_nic_init so that we won't go further in the
start flow.

The call to iwl_sar_geo_init() was moved to the end of the
iwl_mvm_sar_geo_init() function, after the table revision is assigned
to the FW command. But the revision is only known after
iwl_sar_geo_init() is called, so we were always assigning zero to it.
Fix that by moving the assignment code after the iwl_sar_geo_init()
function is called.

Some change conflicts apparently cause a confusion between a local
variable being used to send the PPAG command and the introduction of a
union for this command. Most parts of the local command were never
copied from the stored data, so the FW was getting garbage in the
tables instead of getting valid values.
Fix this by completely removing the local and using only the union
that we have stored in fwrt.

When reading the PPAG table from ACPI, we should store everything in
our fwrt structure, so it can be accessed later. But we had a local
ppag_table variable in the function and were erroneously storing the
enabled/disabled flag in it instead of storing it in the fwrt. Fix
this by removing the local variable and storing everything directly in
fwrt.

The value we receive from ACPI is a long long unsigned integer but the
values should be treated as signed char. When comparing the received
value with ACPI_PPAG_MIN_LB/HB, we were doing an unsigned comparison,
so the negative value would actually be treated as a very high number.
To solve this issue, assign the value to our table of s8's before
making the comparison, so the value is already converted when we do
so.

The only thing we do touching the device in hard interrupt context
is, at most, writing an interrupt ACK register, which isn't racing

Thus, avoid disabling interrupts here for potentially long periods

The ucode TLV data may be read-only and should be treated as const
pointers, but currently a few code forcibly cast to the writable
pointer unnecessarily. This gave developers a wrong impression as if
it can be modified, resulting in crashing regressions already a couple
of times.
This patch adds the const prefix to those cast pointers, so that such
attempt can be caught more easily in future.

Multiple structures in the carl9170 driver have alignment
impossible alignment constraints that gcc warns about when
building with 'make W=1':
drivers/net/wireless/ath/carl9170/fwcmd.h:243:2: warning: alignment 1 of 'union <anonymous>' is less than 4 [-Wpacked-not-aligned]
drivers/net/wireless/ath/carl9170/wlan.h:373:1: warning: alignment 1 of 'struct ar9170_rx_frame_single' is less than 2 [-Wpacked-not-aligned]
In the carl9170_cmd structure, multiple members that have an explicit
alignment requirement of four bytes are added into a union with explicit
byte alignment, but this in turn is part of a structure that also has
four-byte alignment.
In the wlan.h header, multiple structures contain a ieee80211_hdr member
that is required to be two-byte aligned to avoid alignmnet faults when
processing network headers, but all members are forced to be byte-aligned
using the __packed tag at the end of the struct definition.
In both cases, leaving out the packing does not change the internal
layout of the structure but changes the alignment constraint of the
structure itself.
Change all affected structures to only apply packing where it does
not violate the alignment requirement of the contained structure.

as nvram file which is a bit too generic.
Add a DMI quirk so that a unique and clearly identifiable nvram file name
is used on the Voyo winpad A15 tablet.
While preparing a matching linux-firmware update I noticed that the nvram
is identical to the nvram used on the Prowise-PT301 tablet, so the new DMI
quirk entry simply points to the already existing Prowise-PT301 nvram file.

The Predia Basic tablet contains quite generic names in the sys_vendor and
product_name DMI strings, without this patch brcmfmac will try to load:
brcmfmac43340-sdio.Insyde-CherryTrail.txt as nvram file which is a bit
too generic.

Incorrect CCK RSSI may cause periodically scan from upper layer.
8821c phy status does NOT has actual value of CCK power. It provides only
lna and vga index. Driver have to use these indexes to calculate
actual RSSI.
