From 5a2b22b40f3052a8898194fd8c235440ad1d85d8 Mon Sep 17 00:00:00 2001 From: Huisong Li Date: Mon, 17 Jan 2022 10:43:01 +0800 Subject: [PATCH] net/hns3: fix mailbox wait time The mailbox wait time can be specified at runtime. But the variable that controls this time are not initialized when the variable isn't designated or is specified as an invalid value, which will fail to initialize device in the case where no device is bound to initialize the device.
