Subject: [PATCH 2/3] ibmvcsci: display default value for max_id, max_lun and max_channel.
Date: Thu, 10 Sep 2015 11:23:13 +0200	[thread overview]
Message-ID: <1441876994-16821-2-git-send-email-lvivier@redhat.com> (raw)
In-Reply-To: <1441876994-16821-1-git-send-email-lvivier@redhat.com>

As devices with values greater than that are silently ignored,
this gives some hints to the sys admin to know why he doesn't see
his devices...
