Subject: [PATCH net-next 08/13] bnx2x: IGU parse error cause probe failure
Date: Sun, 2 Dec 2012 16:05:52 +0200 [thread overview]
Message-ID: <1354457157-4730-9-git-send-email-yuvalmin@broadcom.com> (raw)
In-Reply-To: <1354457157-4730-1-git-send-email-yuvalmin@broadcom.com>
From: Barak Witkowski <barak@broadcom.com>
If IGU parse error is encountered during the probing process, the error
propagates and the probe gracefully fails (until now, such errors were ignored,
later causing mischief).
