92c70a958b mwifiex: fix for unaligned reads
Using the accessor function e.g. get_unaligned_le32 instead of
le32_to_cpu to avoid the unaligned access. This is for the
architectures that don't handle the unaligned memory access

92ca4f92ec mwifiex: fix error handling in mwifiex_create_custom_regdomain
smatch reports:

sta_cmdresp.c:1053 mwifiex_create_custom_regdomain() warn: possible memory leak of 'regd'

Indeed, mwifiex_create_custom_regdomain() returns NULL in the
case that channel is missing in the TLV without freeing regd.

Moreover, some other error paths in this function return ERR_PTR
values which are assigned without checking to the regd field in
the mwifiex_adapter struct.  The latter is only null-checked where
used.

Fix by freeing regd in the error path, and only update
priv->adapter->regd if the returned pointer is valid.

902831a762 mwifiex: Fixed endianness problem for big endian platform
The driver sends and recives information to and from the firmware.
Correct endianness should be ensured as firmware follows little
endian format and host can be little/big endian.

8cfb86003d mwifiex: Reduce endian conversion for REG Host Commands
For multiple REG Host Commands (e.g HostCmd_CMD_802_11_EEPROM_ACCESS,
HostCmd_CMD_MAC_REG_ACCESS etc.) "cpu_to_leX"-converted values are
saved to driver. So, "leX_to_cpu" conversion is required too many
times afterwards in driver.

This patch reduces the endian: conversion without saving "cpu_to_leX"
converted values in driver. This will convert endianness in prepare
command and command response path.

3ee7128579 mwifiex: add get_antenna support for cfg80211
Since commit de3bb771f4 ("cfg80211: add more warnings for inconsistent
ops") the wireless core warns if a driver implements a cfg80211 callback
but doesn't implements the inverse operation.

The mwifiex driver defines a .set_antenna handler but not a .get_antenna
so this not only makes the core to print a warning when creating a new
wiphy but also the antenna isn't reported to user-space apps such as iw.

This patch queries the antenna to the firmware so is properly reported to
user-space. With this patch, the wireless core does not warn anymore and:

$ iw phy phy0 info | grep Antennas
        Available Antennas: TX 0x3 RX 0x3
        Configured Antennas: TX 0x3 RX 0x3

c70ca8cb9a mwifiex: factor out mwifiex_cancel_pending_scan_cmd
Releasing the scan_pending lock in mwifiex_check_next_scan_command
introduces a short window where pending scan commands can be removed
or added before removing them all in mwifiex_cancel_pending_scan_cmd.
I think this is safe, since the worst thing to happen is that a
pending scan cmd is removed by the command handler. Adding new scan
commands is not possible while one is pending, see scan_processing flag.
Since all commands are removed from the queue anyway, we don't care if
some commands are removed by a different code path earlier, the final
state remains the same.
I assume, that the critical section needed for the check has been
extended over clearing the pending scan queue out of convenience. The
lock was already held and releasing it and grab it again was just
more work. It doesn't seem to be necessary because of concurrency.
