From 0393009ec84e0f22d854e8e11e630d393d44efe9 Mon Sep 17 00:00:00 2001 From: Alexandru Ardelean Date: Thu, 15 Feb 2018 15:15:58 +0100 Subject: [PATCH] net: uqmi: fix blocking in endless loops when unplugging device If you unplug a QMI device, the /dev/cdc-wdmX device disappears but uqmi will continue to poll it endlessly. Then, when you plug it back, you have 2 uqmi processes, and that's bad, because 2 processes talking QMI to the same device [and the same time] doesn't seem to work well.
