Subject: ipc/sem.c: use ERR_CAST
From: Julia Lawall <julia@xxxxxxx>
Use ERR_CAST(x) rather than ERR_PTR(PTR_ERR(x)). The former makes more
clear what is the purpose of the operation, which otherwise looks like a
no-op.
The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

type T;
T x;
identifier f;

T f (...) { <+...
- ERR_PTR(PTR_ERR(x))

expression x;

- ERR_PTR(PTR_ERR(x))
+ ERR_CAST(x)
