From 73a88814542d3f5b8973f3db9d7f380bd29957c4 Mon Sep 17 00:00:00 2001 From: Tilman Schmidt Date: Sat, 22 Apr 2006 02:35:30 -0700 Subject: [PATCH] isdn4linux: Siemens Gigaset base driver: fix disconnect handling Fix a possible Oops in the Siemens Gigaset base driver when the device is unplugged while an ISDN connection is still active, and makes sure that the isdn4linux link level (LL) is properly informed if a connection is broken by the USB cable being unplugged. - Avoid unsafe checks of URB status fields outside the URB completion handlers, keep track of in-use URBs myself instead. - If an isochronous transfer URB completes with status==0, also check the status of the frame descriptors. - Verify length of interrupt messages received from the device. - Align the length limit on transmitted AT commands with the device documentation. - In case of AT response receive overrun, keep newly arrived instead of old unread data. - Remove redundant check of device ID in the USB probe function. - Correct and improve some comments and formatting.
