From c800460086d1db3579b747d9297cecd2bbf70119 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Mon, 3 Apr 2017 21:25:22 +0300 Subject: [PATCH] qed: Add a missing error code We should be returning -ENOMEM if qed_mcp_cmd_add_elem() fails. The current code returns success. Fixes: 4ed1eea82a21 ("qed: Revise MFW command locking") Signed-off-by: Dan Carpenter Acked-by: Tomer Tayar Signed-off-by: David S.
