e1000e: fix pci-device enable-counter balance
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 Cc: Bruce Allan <bruce.w.allan@intel.com> CC: Stable <stable@kernel.org> Signed-off-by: Konstantin Khlebnikov <khlebnikov@openvz.org> Acked-by: Rafael J.
