Subject: [PATCH 4.4 027/137] net: jme: fix suspend/resume on JMC260

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Diego Viola <diego.viola@...il.com>

[ Upstream commit ee50c130c82175eaa0820c96b6d3763928af2241 ]

The JMC260 network card fails to suspend/resume because the call to
jme_start_irq() was too early, moving the call to jme_start_irq() after
the call to jme_reset_link() makes it work.

Prior this change suspend/resume would fail unless /sys/power/pm_async=0
was explicitly specified.
