[linux-yocto] [PATCH 29/34] i2c: i801: Remove pci_enable_device() call from i801_resume()

From: Jarkko Nikula <jarkko.nikula at linux.intel.com>

Since pci_disable_device() is not called from i801_suspend() and power
state is set already it means that subsequent pci_enable_device() calls do
practically nothing but monotonically increase struct pci_dev enable_cnt.
