3.19.8-ckt20 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Diego Viola <diego.viola@gmail.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.

Relevant bug report: https://bugzilla.kernel.org/show_bug.cgi?id=112351
