linux-next: build failure after merge of the selinux tree

Hi all,

After merging the selinux tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

fs/io_uring.c: In function 'io_init_req':
fs/io_uring.c:7069:3: error: 'ret' undeclared (first use in this function); did you mean 'req'?
7069 | ret = security_uring_override_creds(req->creds);
| ^~~
| req
fs/io_uring.c:7069:3: note: each undeclared identifier is reported only once for each function it appears in

Caused by commit

cdc1404a4046 ("lsm,io_uring: add LSM hooks to io_uring")

interacting with commit

1e1e4658e108 ("io_uring: init opcode in io_init_req()")

from the block tree.

I have applied the following merge fix patch:

From: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>
Date: Tue, 5 Oct 2021 14:01:10 +1100
Subject: [PATCH] fixup for "io_uring: init opcode in io_init_req()"
