commit e9a2d81b17 upstream.
gs_destroy_candev() erroneously calls kfree() on a struct gs_can *, which is
allocated through alloc_candev() and should instead be freed using
free_candev() alone.
The inappropriate use of kfree() causes the kernel to hang when
gs_destroy_candev() is called.
Only the struct gs_usb * which is allocated through kzalloc() should be freed
using kfree() when the device is disconnected.
