Subject: [PATCH] Staging: comedi: Remove parentheses around right side assignment
Date: Fri, 13 Mar 2015 14:29:30 +0300 [thread overview]
Message-ID: <20150313112930.GA2597@haneen-vb> (raw)
Parentheses are not needed around the right hand side of an assignment.
This patch remove parenthese of such occurences. Issue was detected and
solved using the following coccinelle script:
@rule1@
identifier x, y, z;
expression E1, E2;
@@
(
x = (y == z);
|
x = (E1 == E2);
|
x =
-(
...
-)
;
)
