Subject: PCI: use fixed-up device class when configuring device
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f79b1b146b52765ee38bfb91bb14eb850fa98017;p=linux-beck.git

PCI: use fixed-up device class when configuring device

The device class may be changed after the fixup, so re-read the class
value from pci_dev when configuring the device.  Otherwise some devices
such as JMicron SATA controller won't work.
