When using single_open() for opening, single_release() should be
used instead of seq_release(), otherwise there is a memory leak.
This is detected by Coccinelle semantic patch.

When calling debugfs functions, there is no need to ever check the
return value. The function can work or not, but the code logic should
never do something different based on this.

Use debugfs to dump register and btcoex status, and also write registers
and h2c.
We create topdir in /sys/kernel/debug/rtlwifi/, and use the MAC address
as subdirectory with several entries to dump mac_reg, bb_reg, rf_reg etc.
An example is
/sys/kernel/debug/rtlwifi/00-11-22-33-44-55-66/mac_0
This change permits examination of device registers in a dynamic manner,
a feature not available with the current debug mechanism.

This is merged by Ping-Ke Shih from commit a221cb0911 ("staging:
rtlwifi: Remove unnecessary parentheses"), and original commit log
is reserved below.
Remove unnecessary parentheses to comply with preferred coding style for
the linux kernel and avoid the following checkpatch's message:
'CHECK: Unnecessary parentheses around'.

The debugging macros contain a parameter COMP_XX that could be used as a
mask; however, the code turns all these various bits on at the same time.
This change implements them as a proper mask, and adds module parameters
to set the mask at load time.
The current name "debug" for the debug level has been changed to
"debug_level" to better differentiate it from "debug_mask".
The debug routines have also been changed to interrogate the structure
that is loaded at entry time. As a result, the structure rtl_debug is no
longer needed, and all references to it are deleted.

These two debugging formss implement debugging using rather complicated
macro constructions. These are replaced with compiled code that is easier

This debugging macro can expand to a lot of code.
Make it a function to reduce code size.

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.
