Subject: Revert "cred: add missing return error code when set_cred_ucounts() failed"
From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>
This reverts commit 0855952ed4f1a6861fbb0e5d684efd447d7347c9 which is
commit 5e6b8a50a7cec5686ee2c4bda1d49899c79a7eae upstream.
The "original" commit 905ae01c4ae2 ("Add a reference to ucounts for each
cred"), should not have been applied to the 5.10.y tree, so revert it,
and the follow-on fixup patches as well.
