Subject: staging: rtl8192u: remove extra parentheses around right bit shift operation
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9eb9e69536ba00d2dbe4f481b20ced67053a6c08;p=openwrt%2Fstaging%2Fblogic.git

staging: rtl8192u: 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;
type t;
expression e;
@@

t i =
-(e
+e
>>
-c);
+c;

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

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

Some coding style issues were handled manually to avoid
checkpatch warnings and errors.
