From fd07a62d58c16b1fdd46f4099791c5bd242908c3 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Thu, 17 Aug 2017 10:01:07 +0100 Subject: [PATCH] net: hns3: ensure media_type is unitialized Media type is only set if h->ae_algo->ops->get_media_type is called so there is a possibility that media_type is uninitialized when it is used a switch statement. Fix this by initializing media_type to HNAE3_MEDIA_TYPE_UNKNOWN.
