The code in the BRCM80211 BRCMSMAC driver is using the legacy GPIO API to to a complex check of the validity of the base of the GPIO chip and whether it is present at all and then adding an offset to the base of the chip. Use the existing function to obtain a GPIO line internally from a GPIO chip so we can use the offset directly and modernize the code to use GPIO descriptors instead of integers from the global GPIO numberspace.
