[PATCH 6.12 057/117] cifs: Fix TCP_Server_Info::credits to be signed

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

6.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: David Howells <dhowells@redhat.com>

commit 5b2ff4873aeab972f919d5aea11c51393322bf58 upstream.

Fix TCP_Server_Info::credits to be signed, just as echo_credits and
oplock_credits are.  This also fixes what ought to get at least a
compilation warning if not an outright error in *get_credits_field() as a
pointer to the unsigned server->credits field is passed back as a pointer
to a signed int.
