In https://bugzilla.redhat.com/show_bug.cgi?id=994438 and https://bugzilla.redhat.com/show_bug.cgi?id=970480 we received different reports of e100 throwing the following warning: [<c06a0ba5>] ? pci_disable_device+0x85/0x90 [<c044a153>] warn_slowpath_fmt+0x33/0x40 [<c06a0ba5>] pci_disable_device+0x85/0x90 [<f7fdf7e0>] __e100_shutdown+0x80/0x120 [e100] [<c0476ca5>] ? check_preempt_curr+0x65/0x90 [<f7fdf8d6>] e100_suspend+0x16/0x30 [e100] [<c06a1ebb>] pci_legacy_suspend+0x2b/0xb0 [<c098fc0f>] ? wait_for_completion+0x1f/0xd0 [<c06a2d50>] ? pci_pm_poweroff+0xb0/0xb0 [<c06a2de4>] pci_pm_freeze+0x94/0xa0 [<c0767bb7>] dpm_run_callback+0x37/0x80 [<c076a204>] ? pm_wakeup_pending+0xc4/0x140 [<c0767f12>] __device_suspend+0xb2/0x1f0 [<c076806f>] async_suspend+0x1f/0x90 [<c04706e5>] async_run_entry_fn+0x35/0x140 [<c0478aef>] ? wake_up_process+0x1f/0x40 [<c0464495>] process_one_work+0x115/0x370 [<c0462645>] ? start_worker+0x25/0x30 [<c0464dc5>] ? manage_workers.isra.27+0x1a5/0x250 [<c0464f6e>] worker_thread+0xfe/0x330 [<c0464e70>] ? manage_workers.isra.27+0x250/0x250 [<c046a224>] kthread+0x94/0xa0 [<c0997f37>] ret_from_kernel_thread+0x1b/0x28 [<c046a190>] ? insert_kthread_work+0x30/0x30 This patch removes pci_disable_device() from __e100_shutdown(). pci_clear_master() is enough.
