Subject: [PATCH 4.9 27/51] r8152: dont execute runtime suspend if the tx is not empty
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: hayeswang <hayeswang@...ltek.com>
[ Upstream commit 6a0b76c04ec157c88ca943debf78a8ee58469f2d ]
Runtime suspend shouldn't be executed if the tx queue is not empty,
because the device is not idle.
