Subject: e1000e: fix pci-device enable-counter balance
From: Konstantin Khlebnikov <khlebnikov@xxxxxxxxxx>
commit 4e0855dff094b0d56d6b5b271e0ce7851cc1e063 upstream.
This patch removes redundant and unbalanced pci_disable_device() from
__e1000_shutdown(). pci_clear_master() is enough, device can go into
suspended state with elevated enable_cnt.
Bug was introduced in commit 23606cf5d1192c2b17912cb2ef6e62f9b11de133
("e1000e / PCI / PM: Add basic runtime PM support (rev. 4)") in v2.6.35
