As this quantity is usually zero, this +output is not needed. In fact, there will be a report if the status is +not zero, thus the debug line in question could probably be deleted. +Rather than taking that action, I have changed it to only be printed +when the newly added RTL8XXXU_DEBUG_INTERRUPT bit is set in the debug +mask. + +Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> +Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> +Signed-off-by: Kalle Valo <kvalo@codeaurora.org> +--- + drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu.h | 1 + + drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_core.c | 3 ++- + 2 files changed, 3 insertions(+), 1 deletion(-) + +--- a/drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu.h ++++ b/drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu.h +@@ -29,6 +29,7 @@ + #define RTL8XXXU_DEBUG_H2C 0x800 + #define RTL8XXXU_DEBUG_ACTION 0x1000 + #define RTL8XXXU_DEBUG_EFUSE 0x2000 ++#define RTL8XXXU_DEBUG_INTERRUPT 0x4000 + + #define RTW_USB_CONTROL_MSG_TIMEOUT 500 + #define RTL8XXXU_MAX_REG_POLL 500 +--- a/drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_core.c ++++ b/drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_core.c +@@ -5375,7 +5375,8 @@ static void rtl8xxxu_int_complete(struct + struct device *dev = &priv->udev->dev; + int ret; + +- dev_dbg(dev, "%s: status %i\n", __func__, urb->status); ++ if (rtl8xxxu_debug & RTL8XXXU_DEBUG_INTERRUPT) ++ 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); |
