Date: Fri, 13 Nov 2015 10:52:41 +0100 From: Ivan Vecera <ivecera@...hat.com> To: netdev@...r.kernel.org Cc: sriharsha.basavapatna@...gotech.com, sathya.perla@...gotech.com, ajit.khaparde@...gotech.com, padmanabh.ratnakar@...gotech.com Subject: [PATCH net] be2net: check properly status in lancer_cmd_get_file_len() The lancer_cmd_get_file_len() calls lancer_cmd_read_object() to get the current size of registers for ethtool registers dump. The size is stored in data_read but only when the returned status is 0 otherwise it is uninitialized thus random.
