[PATCH] watchdog: hpwdt: add support for iLO5

From: Brian Boylston
Date: Mon Sep 26 2016 - 14:59:42 EST


iLO5 will offer the same watchdog timer as previous generations, but the
PCI subsystem vendor ID will be PCI_VENDOR_ID_HP_3PAR (0x1590) instead of
PCI_VENDOR_ID_HP (0x103c). Add 0x1590 to the whitelist and be more
specific when ignoring the 103c,1979 device.
