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. Signed-off-by: Chase Southwood <chase.southwood@xxxxxxxxx> Cc: H Hartley Sweeten <hsweeten@xxxxxxxxxxxxxxxxxxx> --- This is a (small) first patchset for my more complete cleanup of addi_apci_1564 driver. Hartley, I'd appreciate any review you have wrt these specific patches, but also whether I have chosen a good place to start. .../comedi/drivers/addi-data/hwdrv_apci1564.c | 79 +++++++++++----------- 1 file changed, 39 insertions(+), 40 deletions(-) diff --git a/drivers/staging/comedi/drivers/addi-data/hwdrv_apci1564.c b/drivers/staging/comedi/drivers/addi-data/hwdrv_apci1564.c index 9c86b02..4db3bea 100644 --- a/drivers/staging/comedi/drivers/addi-data/hwdrv_apci1564.c +++ b/drivers/staging/comedi/drivers/addi-data/hwdrv_apci1564.c @@ -76,7 +76,7 @@ #define APCI1564_TIMER_WARN_TIMEBASE_REG 0x64 /* - * devpriv->iobase Register Map + * dev>iobase Register Map */ #define APCI1564_TCW_REG(x) (0x00 + ((x) * 0x20)) #define APCI1564_TCW_RELOAD_REG(x) (0x04 + ((x) * 0x20)) @@ -239,13 +239,13 @@ static int apci1564_timer_config(struct comedi_device *dev, outl(0x0, devpriv->i_IobaseAmcc + APCI1564_DO_IRQ_REG);
