X-Git-Tag: firefly_0821_release~3680^2~2356^2~469
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=db7c275d9ffd2c58648b1bf023ab62cf993ddfac;p=firefly-linux-kernel-4.4.55.git

staging: comedi: adl_pci6208: remove pci6208_pci_setup()

Refactor pci6208_pci_setup() into the attach function. This
function simply enables the pci device and gets the PCI iobase
address used by the driver. There's no need for a separate
function to handle this.
