Greg, I'm sending two patches for the usbserial NULL pointer dereference we discussed last week: http://marc.theaimsgroup.com/?l=linux-kernelm=113216151918308w=2 The first patch adds the missing checks you suggested we should use in usb-serial driver's entry points, to avoid NULL pointer

2005-11-22 Thread Luiz Fernando Capitulino
Fixes open()/close() race-condition in the access of the port structure. When the race happens, the port in use becomes invalid, and the user must try to get the next free port (repluging the device, for example). Described in more detail in this thread:
