From 87683e22c646e563061a91f4a0106e6913acebf8 Mon Sep 17 00:00:00 2001 From: Oliver Neukum Date: Fri, 7 Sep 2012 23:28:30 +0200 Subject: [PATCH] PCI: pciehp: Always implement resume, regardless of pciehp_force param Previously, the driver ignored resume unless the pciehp_force module_param was specified. On some laptops that means that interrupts are not delivered after S3, so card removals and insertions are not handled. This patch makes the driver handle resume regardless of pciehp_force.
