From c9b1420c397314a4855af70aadb79450d1bd6fe0 Mon Sep 17 00:00:00 2001 From: Chase Southwood Date: Tue, 15 Apr 2014 00:53:55 -0500 Subject: [PATCH] staging: comedi: addi_apci_1564: remove use of devpriv->iobase devpriv->iobase is currently being used to hold the iobase address used to read/write the board's registers. The same address is stored in the comedi_device dev->iobase. We use that instead. The eventual goal is to decrease the driver's use of the struct addi_private, so that it may eventually use a much slimmer specialized private struct instead, as the other addi_apci_* drivers do.
