2597864233 staging: rtl8712: remove extra parentheses around right bit shift operation
Removes extra parentheses around bitwise right shift operation.
The cases handled are  when the resultant value is assigned to
a variable or when a shift operation is carried out for a function
argument. The issues were detected and resolved using the following
coccinelle script:

@@
expression e, e1;
constant c;
@@

e =
-(e1
+e1
>>
-c);
+c;

@@
identifier i;
constant c;

@@
expression e, e1;
identifier f;
constant c;

e1 = f(...,
-(e
+e
>>
-c)
+c
,...);

ddcb81e741 staging: rtl8712: merge lines and remove unused variable for immediate return
This patch merge two lines in a single line if immediate return is found.
Unused variables in each case were removed manually as they are no longer
needed.

This is done using Coccinelle. Semantic patch used for this is as
follows :
@@
expression ret;
identifier f;
@@

-ret =
+return
     f(...);
-return ret;

fdfbf7890d staging: rtl8712: remove wrapper function list_insert_tail
list_insert_tail is just an inline wrapper around list_add_tail.  This
patch removes the wrapper and directly uses list_add_tail.

bd9dc62c36 staging: rtl8712: replace kmalloc(..., sizeof(T))
As suggested by Andy Shevchenko on driverdev-devel, replace
v = ... sizeof(struct type_of_v) -> sizeof(*v)

Based on a cocci patch along the lines of

type T;
expression E;
identifier V;
@@

T *V;
...
- V = kmalloc(sizeof(T), E);
+ V = kmalloc(sizeof(*V), E);

91d435fe36 staging: rtl8712: remove _malloc()
This patch removes all usage of _malloc() and the function itself. Most
uses are straightforward replacements by kmalloc(..., GFP_ATOMIC),
because this was the definition of _malloc(). In a few places it
was possible to use kzalloc() or memdup_user.

A further improvement would be to replace GFP_ATOMIC with GFP_KERNEL
where possible.

Verified by compilation only.

Initial replacement done by running a Coccinelle script along the lines
of:

@@
type T;
expression E;
identifier V;
@@
- V = (T) _malloc(E);
+ V = kmalloc(E, GFP_ATOMIC);

@@
expression E, E1;
@@
- E1 = _malloc(E);
+ E1 = kmalloc(E, GFP_ATOMIC);

8ffca9eae6 staging: r8712u: Remove useless return variables
This patch remove variables that are initialized with a constant,
are never updated, and are only used as parameter of return.
Return the constant instead of using a variable.

2865d42c78 staging: r8712u: Add the new driver to the mainline kernel
This code is for a completely new version of the Realtek 8192 USB devices
such as the D-Link DWA-130. The Realtek code, which was originally for
Linux, Windows XP and Windows CE, has been stripped of all code not needed
for Linux. In addition, only one additional configuration variable, which
enables AP mode, remains.
