strcpy() performs no bounds checking on the destination buffer. This

to all kinds of misbehaviors. The safe replacement is strscpy() but in
this case it is simpler to use the "%*ph" format specifier.

Moreover, with the "0x%02X " in the sprintf followed by the strcat, the
msg buffer (now removed) can print 128/5 values (25 hex values). So, the

staging: r8188eu: remove include/odm_debug.h

Remove include/odm_debug.h in its entirety. To do this, first:

(1) Remove DebugLevel and DebugComponents members from the struct
    odm_dm_struct definition, and any uses of these elsewhere in
    the driver.

(2) Remove the function ODM_InitDebugSetting from hal/odm_debug.c
    whilst leaving the file in place for now as it contains a global
    which is still used and will be removed by further cleanup code.
    Also remove all of its callers. All the function does is set the
    members mentioned above.

(3) Remove the now redundant constants and their usages:
    ODM_CMNINFO_DBG_LEVEL
    ODM_CMNINFO_DBG_COMP
    HW_DEF_ODM_DBG_FLAG
    HW_DEF_FA_CNT_DUMP
    This includes usage within a few hexadecimal ioctl switch cases
    in os_dep/ioctl_linux.c (although only the call itself within
    0x11 as it contains additional code currently).

(4) Finally, remove the file itself and its inclusion within
    include/odm_precomp.h, as none of the remaining content is used
    from anywhere else in the driver.

staging: r8188eu: fix include directory mess

The driver seems to want to include a specific directory for all include
files on the build path, but that breaks when trying to build only the
module directory, or when building with "O=" option.

Fix this up by making all includes for the driver be relative locations.

It is just a wrapper around kfree(), so just replace all calls with
kfree() instead.  The pointer is also set to NULL and the length set to
0 to emulate the original logic, just to be "safe" as I do not have a
device to test with, but odds are that can be removed later on.

staging: rtl8723bs: remove unused BIT macros definitions

BIT(x) macro used all over the driver is defined in
include/vsdo/bit.h as

- #define BIT(nr) (UL(1) << (nr))

which is safer than the local BIT macros declared.
Local macros shift a signed integer which brings
unespected results. For example:

(unsigned long)(1 << 31) => 0xffffffff80000000

shift.c:

int main() {
        printf("%lx\n", (unsigned long)(1 << 31));
        printf("%lx\n", (unsigned long)(1U << 31));
        return 0;
}

...

$ ./shift
ffffffff80000000
80000000

...

So just remove redundant, less safe macro declarations.
