From: Colin Ian King Date: Thu, 17 Aug 2017 09:01:07 +0000 (+0100) Subject: net: hns3: ensure media_type is unitialized X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fd07a62d58c16b1fdd46f4099791c5bd242908c3;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git 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.
