[PATCH 8/20] drivers/parport: Use kzalloc

[Julia Lawall <julia@diku.dk>]

From: Julia Lawall <julia@diku.dk>

Use kzalloc rather than the combination of kmalloc and memset.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@
expression x,size,flags;
statement S;
@@

-x = kmalloc(size,flags);
+x = kzalloc(size,flags);
 if (x == NULL) S
-memset(x, 0, size);
// </smpl>
