Hi ,
I'm adding the hot-plug support to the joystick input driver, but when
running in "multi-mode" with "linux-fusion-8.7.0", I'm getting a crash
after the first "plug/unplug/plug" below is the full trace:

(gdb)
in the src/core/input.c there is a call to " fusion_call_destroy(
&shared->call )" in "dfb_input_remove_device()"
but I was not able to understand how the "shared->call" is recreated after
the device is re-plugged.
regards.
Haithem.
