drivers/atm: Correct redundant test
Author: Julia Lawall <julia@diku.dk>
str has already been tested. It seems that this test should be on the
recently returned value snr.
A simplified version of the semantic match that finds this problem is as
follows: (http://www.emn.fr/x-info/coccinelle/)
//
@r exists@
local idexpression x;
expression E;
@@
if (x == NULL || ...) { ... when forall
return ...; }
... when != \(x=E\|x--\|x++\|--x\|++x\|x-=E\|x+=E\|x|=E\|x&=E\|&x\)
(
*x == NULL
|
*x != NULL
)
