From c76a23da8e9a39222c4a7c29b0c5348cd8902a2b Mon Sep 17 00:00:00 2001 From: Elina Pasheva Date: Tue, 12 May 2009 13:12:37 -0700 Subject: USB: serial: sierra driver interrupt urb resubmit fix - Fixed a problem when re-submitting urb from interrupt callback in function sierra_instat_callback(). This suppresses also issuing of error messages in /var/log/kern.log - Removed redundant debug message at the beginning of sierra_instat_callback() function - Changed a debug message to be an error message Signed-off-by: Elina Pasheva Signed-off-by: Greg Kroah-Hartman --- drivers/usb/serial/sierra.c | 7 +++---- 1 file changed, 3 insertions(+), 4 deletions(-) (limited to 'drivers/usb/serial/sierra.c') diff --git a/drivers/usb/serial/sierra.c b/drivers/usb/serial/sierra.c index 9d11fe47633b..bcfe0ac1e221 100644 --- a/drivers/usb/serial/sierra.c +++ b/drivers/usb/serial/sierra.c @@ -556,7 +556,6 @@ static void sierra_instat_callback(struct urb *urb) struct sierra_port_private *portdata = usb_get_serial_port_data(port); struct usb_serial *serial = port->serial; - dev_dbg(&port->dev, "%s\n", __func__); dev_dbg(&port->dev, "%s: urb %p port %p has data %p\n", __func__, urb, port, portdata); @@ -600,12 +599,12 @@ static void sierra_instat_callback(struct urb *urb) dev_dbg(&port->dev, "%s: error %d\n", __func__, status); /* Resubmit urb so we continue receiving IRQ data */ - if (status != -ESHUTDOWN) { + if (port->port.count && status != -ESHUTDOWN && status != -ENOENT) { urb->dev = serial->dev; err = usb_submit_urb(urb, GFP_ATOMIC); if (err) - dev_dbg(&port->dev, "%s: resubmit intr urb " - "failed.
