[PATCH v2 2/2] cxl/mbox: Use mapped errno to determine command status

From: Li Ming

Date: Mon Nov 02 2026 - 21:44:38 EST


cxl_mbox_cmd_rctable already maps all mailbox command return codes to
errno values. Use the returned errno directly instead of checking
mailbox return codes separately to determine whether a command succeeded
or failed.
