Staging: vme: devices: Use kasprintf
This patch uses kasprintf which combines kmalloc and sprintf.
kasprintf also takes care of the size calculation.
This is done using Coccinelle. Semantic patch used is as follows:
@@
expression a,flag;
expression list args;
statement S;
@@
a =
- \(kmalloc\|kzalloc\)(...,flag)
+ kasprintf (flag,args)
<... when != a
if (a == NULL || ...) S
...>
- sprintf(a,args);
