I found a memory leak in sierra_release() (well sierra_probe() I guess)
that looses 8 bytes each time the driver releases a device.
Here is the patch to fix it.
diff --git a/drivers/usb/serial/sierra.c b/drivers/usb/serial/sierra.c
index 01d882c..76ef95b 100644
--- a/drivers/usb/serial/sierra.c
+++ b/drivers/usb/serial/sierra.c
@@ -959,6 +959,7 @@ static void sierra_release(struct usb_serial *serial)
continue;
kfree(portdata);
}
+ kfree(serial->private);
}
#ifdef CONFIG_PM

Looks sensible to me, but needs a signed-off-by and CC to linux-usb.

Oh yeah. I shouldn't send patches at the end of the day.
I will try again.
