The return value of kzalloc on failure of allocation of memory should
be -ENOMEM and not -1.
Found using Coccinelle. A simplified version of the semantic patch
used is:
//<smpl>
@@
expression *e;
@@
e = kzalloc(...);
if (e == NULL) {
...
return
- -1
+ -ENOMEM
;
}
//</smpl>
The single call site only checks that the return value is not 0,
hence no change is required at the call site.
