In commit 6773386f97 ("rtlwifi: rtl8192c-common: Fix "BUG: KASAN:"),
a BUG detected when CONFIG_KASAN=y was fixed by reordering the layouts
of struct rtl_pci_priv, and struct rtl_usb_priv so that the variables
used by both PCI and USB drivers have the same offsets in both structs.
The better fix of relocating the critical variables into struct rtl_priv
was deferred as these changes do not have to be applied to stable
kernels.
This change also removes CamelCase variables with pLed0 => pled0.

Some devices with RTL8732BE wifi/Bluetooth adapters are shipped with only
a single antenna. On a subset of these, the EEPROM is incorectly coded
to indicate the wrong connection. The resulting problems have been fixed
for wifi. This change handles them for BT.

This is a step toward eliminating the RT_TRACE macros. Those calls that
have DBG_EMERG as the level are always logged, and they represent error
conditions, thus they are replaced with pr_err().

This macro can be replaced with WARN_ONCE. In addition to using a
standard debugging macro for these critical errors, we also get
a stack dump.
In rtl8821ae/hw.c, a senseless comment was removed, and an incorrect
indentation was fixed.
This patch also fixes two places in each of rtl8192ee, rtl8723be,
and rtl8821ae where the logical condition was incorrect.

Only rtl8821ae implements WOWLAN; however, the other drivers may receive
a call requesting information about this mode. The other drivers need to
ignore the request rather than logging that the default branch of the
switch statement has been reached.

RT_TRACE does not add a newline to the end of a message and always
emits at KERN_DEBUG so these are susceptible to message interleaving
from other processes without the newline.

There are nine copies of the _rtl88ee_read_adapter_info() function,
and most but not all of them cause a build warning in some configurations:
rtl8192de/hw.c: In function '_rtl92de_read_adapter_info':
rtl8192de/hw.c:1767:12: error: 'hwinfo' may be used uninitialized in this function [-Werror=maybe-uninitialized]
rtl8723ae/hw.c: In function '_rtl8723e_read_adapter_info.constprop':
rtlwifi/rtl8723ae/hw.c:1654:12: error: 'hwinfo' may be used uninitialized in this function [-Werror=maybe-uninitialized]
The problem is that when rtlefuse->epromtype is something other than
EEPROM_BOOT_EFUSE, the rest of the function uses undefined data, resulting
in random behavior later.
Apparently, in some drivers, the problem was already found and fixed
but the fix did not make it into the others.
This picks one approach to deal with the problem and applies identical
code to all 9 files, to simplify the later consolidation of those.

A number of new laptops have been delivered with only a single antenna.
In principle, this is OK; however, a problem arises when the on-board
EEPROM is programmed to use the other antenna connection. The option
of opening the computer and moving the connector is not always possible
as it will void the warranty in some cases. In addition, this solution
breaks the Windows driver when the box dual boots Linux and Windows.
A fix involving a new module parameter has been developed. This commit
adds the new parameter and implements the changes needed for the driver.

Now that a new mac80211-based driver for Realtek devices has been submitted,
it is time to reorganize the directories. Rather than having directories
rtlwifi and rtl818x be in drivers/net/wireless/, they will now be in
drivers/net/wireless/realtek/. This change simplifies the directory
structure, but does not result in any configuration changes that are
visable to the user.
