Subject: staging: comedi: addi_apci_1516: remove use of struct addi_private
X-Git-Tag: firefly_0821_release~3680^2~1519^2~409
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=a29cd0eedf30779675d6a1a678da1ff55d681494;p=firefly-linux-kernel-4.4.55.git

staging: comedi: addi_apci_1516: remove use of struct addi_private

The only private data this driver has is the iobase address for the
watchdog. Create a local struct to hold this information in dev->private
and remove the need for struct addi_private from the "common" code.
