[PATCH] set eventfd_link_misc.minor=MISC_DYNAMIC_MINOR

For miscdevices, the major device_no is same, so the minor device_no should be set to ditinguish different misc devices;  if not set the minor, it may fail while insmod due to the default minor value, 0, has been used by other miscdevice. MISC_DYNAMIC_MINOR means to let Linux kernel dynamically assign one minor devide number while loading.
