[PATCH 52/90] staging: comedi: cb_pcimdas: remove BADR4 from the private data

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

The pci resource bar 4 address is only needed to initialize the
8255 subdevice. Use a local variable to hold it and remove it
from the private data.
