The two patches inside the debdiff fix these bugs:
* First issue is that usb_modeswitch_dispatcher.c crashes when a device
presented to it has no USB interface 0. This is caused by improper
checking for a NULL pointer returned by a interface-lookup function. It
is fixed by adding a null-check and gracefully exiting the program if
there is no interface 0. This should be consistent with how the upstream
Tcl script handled this.
* Second issue is that usb_modeswitch_dispatcher.c writes an unexpected
literal "(null)" string to usb_modeswitch command line. This suprisingly
does not cause any malfunction, because the argument is ignored by
usb_modeswitch. The problem is caused by assignment of NULL to a
variable where strdup("") should have been used instead. The problem is
fixed by using strdup, which is consistent with how this was handled in
other cases as well.
