From c9008d339bc40301a486ea62f36f106c4b2aad0e Mon Sep 17 00:00:00 2001 From: Thomas Falcon Date: Mon, 6 Aug 2018 21:39:59 -0500 Subject: [PATCH] ibmvnic: Update firmware error reporting with cause string Print a string instead of the error code. Since there is a possibility that the driver can recover, classify it as a warning instead of an error. Signed-off-by: Thomas Falcon Signed-off-by: David S.
