Subject[PATCH 4.14 067/110] amd-xgbe: Restore PCI interrupt enablement setting on resume
Date
4.14-stable review patch.  If anyone has any objections, please let me know.

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

From: Tom Lendacky <thomas.lendacky@amd.com>


[ Upstream commit cfd092f2db8b4b6727e1c03ef68a7842e1023573 ]

After resuming from suspend, the PCI device support must re-enable the
interrupt setting so that interrupts are actually delivered.
