[ALSA] sound/pci: remove unused variable
Author: Julia Lawall <julia@diku.dk>
The variable is_capture is initialized but never used otherwise.
The semantic patch that makes this change is as follows:
(http://www.emn.fr/x-info/coccinelle/)
//
@@
type T;
identifier i;
constant C;
@@
(
extern T i;
|
- T i;
<+... when != i
- i = C;
...+>
)
