From d374c1c1281d6188a0d0676172b1c0e3de35c6e7 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Mon, 12 Jun 2006 12:53:27 -0700 Subject: [sky2] Fix sky2 network driver suspend/resume This fixes two independent problems: it would not save the PCI state on suspend (and thus try to resume a nonexistent state on resume), and while shut off, if an interrupt happened on the same shared irq, the irq handler would react very badly to the interrupt status being an invalid all-ones state.
