The static variable ui_Command is as of right now being cleared to a value of zero between everytime that it writes to a port and then takes a new value from a port. Seems like this zeroing is unnecessary, so we can just remove these lines. Signed-off-by: Chase Southwood <chase.southwood@xxxxxxxxx> --- This sort of thing seems like a copy/paste sort of error to me, but there could as easily be some reason here that I'm missing that this is needed here. My first impression, however, was that this extra clearing is useless. drivers/staging/comedi/drivers/addi-data/hwdrv_apci035.c | 12 ++++-------- 1 file changed, 4 insertions(+), 8 deletions(-) diff --git a/drivers/staging/comedi/drivers/addi-data/hwdrv_apci035.c b/drivers/staging/comedi/drivers/addi-data/hwdrv_apci035.c index 6fca105..9041fdf 100644 --- a/drivers/staging/comedi/drivers/addi-data/hwdrv_apci035.c +++ b/drivers/staging/comedi/drivers/addi-data/hwdrv_apci035.c @@ -182,11 +182,9 @@ static int i_APCI035_ConfigTimerWatchdog(struct comedi_device *dev, else ui_Mode = 0; -/* ui_Command = inl(devpriv->iobase+((i_WatchdogNbr-1)*32)+12); */ ui_Command = 0; -/* ui_Command = ui_Command & 0xFFFFF9FEUL; */ outl(ui_Command, devpriv->iobase + ((i_WatchdogNbr - 1) * 32) + 12); - ui_Command = 0; + ui_Command = inl(devpriv->iobase + ((i_WatchdogNbr - 1) * 32) + 12); /* Set the reload value */ @@ -224,7 +222,7 @@ static int i_APCI035_ConfigTimerWatchdog(struct comedi_device *dev, } outl(ui_Command, devpriv->iobase + ((i_WatchdogNbr - 1) * 32) + 12); - ui_Command = 0; + ui_Command = inl(devpriv->iobase + ((i_WatchdogNbr - 1) * 32) + 12); /* Disable the hardware trigger */ @@ -235,7 +233,7 @@ static int i_APCI035_ConfigTimerWatchdog(struct comedi_device *dev, ui_Command = ui_Command | (data[5] << 5); } outl(ui_Command, devpriv->iobase + ((i_WatchdogNbr - 1) * 32) + 12); - ui_Command = 0; + ui_Command = inl(devpriv->iobase + ((i_WatchdogNbr - 1) * 32) + 12); /* Disable the hardware gate */ @@ -246,7 +244,7 @@ static int i_APCI035_ConfigTimerWatchdog(struct comedi_device *dev, ui_Command = ui_Command | (data[7] << 7); } outl(ui_Command, devpriv->iobase + ((i_WatchdogNbr - 1) * 32) + 12); - ui_Command = 0; + ui_Command = inl(devpriv->iobase + ((i_WatchdogNbr - 1) * 32) + 12); /* Disable the hardware output */ @@ -266,7 +264,6 @@ static int i_APCI035_ConfigTimerWatchdog(struct comedi_device *dev, devpriv->iobase + ((i_WatchdogNbr - 1) * 32) + 28); } - ui_Command = 0; ui_Command = inl(devpriv->iobase + ((i_WatchdogNbr - 1) * 32) + 12); /* Disable the hardware output */ @@ -277,7 +274,6 @@ static int i_APCI035_ConfigTimerWatchdog(struct comedi_device *dev, outl(ui_Command, devpriv->iobase + ((i_WatchdogNbr - 1) * 32) + 12); /* Enable the watchdog interrupt */ - ui_Command = 0; ui_Command = inl(devpriv->iobase + ((i_WatchdogNbr - 1) * 32) + 12); /* Set the interrupt selection */ -- 1.8.5.3 _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
