From 2b2bbb561f6de45a8d3155e197e46fa199451485 Mon Sep 17 00:00:00 2001 From: Kai-Heng Feng Date: Sun, 13 Jan 2019 19:02:53 +0800 Subject: [PATCH] staging: rtl8712u: Remove dummy reset-resume callback An USB wireless dongle uses rtl8712u stops working after system suspend/resume. When a USB device lost its power during suspend, the USB core knows the power was lost and a reset-resume or a re-probe is required. But rtl8712u provides a dummy reset-resume callback, which gets called and renders the device dead after resume. So remove the reset-resume call back, if power was lost during suspend, let the USB core unbind and probe the device to solve the issue.
