There are many uses of if (rtl8xxxu_debug & <DEFINE>) { dev_info(dev, ...) Emitting debugging information at KERN_INFO is odd. I think it'd be nicer to use dev_dbg for all these cases and as well use some new macro that includes the test Something like: #define rtl8xxxu_dbg(type, fmt, ...) \ do { \ if (rtl8xxxu_debug & (type)) \ dev_dbg(dev, fmt, ##__VA_ARGS__); \ } while (0) > Signed-off-by: Larry Finger <Larry.Finger@xxxxxxxxxxxx> > --- > drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_core.c | 3 ++- > 1 file changed, 2 insertions(+), 1 deletion(-) > > > diff --git a/drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_core.c b/drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_core.c > index 9f6dbb4..236f33c 100644 > --- a/drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_core.c > +++ b/drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_core.c > @@ -5260,7 +5260,8 @@ static void rtl8xxxu_int_complete(struct urb *urb) > struct device *dev = &priv->udev->dev; > int ret; > > - dev_dbg(dev, "%s: status %i\n", __func__, urb->status); > + if (rtl8xxxu_debug & RTL8XXXU_DEBUG_USB) > + dev_dbg(dev, "%s: status %i\n", __func__, urb->status); > if (urb->status == 0) { > usb_anchor_urb(urb, &priv->int_anchor); > ret = usb_submit_urb(urb, GFP_ATOMIC); > > _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
