Subject: [PATCH] smb: client: Return a status code only as a constant in
 cifs_spnego_key_instantiate()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Tue, 7 Oct 2025 16:32:25 +0200

* Return a status code without storing it in an intermediate variable.

* Delete the local variable “ret” and the label “error”
  which became unnecessary with this refactoring.
