Subject: staging: comedi: das08: Use module_comedi_{pci_, }driver
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1e576a5707c95a4fb5927d97ed21582a55f75a82;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

staging: comedi: das08: Use module_comedi_{pci_, }driver

If PCI boards are supported, use the module_comedi_pci_driver() macro to
register the module as a comedi driver and a PCI driver.  Otherwise, if
ISA (or PC/104) boards are supported, use the module_comedi_driver()
macro to register the module as a comedi driver.  Otherwise, this is
only a helper module for an external comedi driver (das08_cs).
