Subject: arch/x86/pci: use kasprintf
From: Julia Lawall <julia@xxxxxxx>
kasprintf combines kmalloc and sprintf, and takes care of the size
calculation itself.
The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@
expression a,flag;
expression list args;
statement S;
@@
a =
- \(kmalloc\|kzalloc\)(...,flag)
+ kasprintf(flag,args)
<... when != a
if (a == NULL || ...) S
...>
- sprintf(a,args);
// </smpl>
