Subject: [PATCH 4.9 04/30] net: natsemi: Fix missing pci_disable_device() in probe and remove

From: Wang Hai <wanghai38@...wei.com>

[ Upstream commit 7fe74dfd41c428afb24e2e615470832fa997ff14 ]

Replace pci_enable_device() with pcim_enable_device(),
pci_disable_device() and pci_release_regions() will be
called in release automatically.
