    sys/dev/uart         uart_core.c 
  Log:
  - Allocate the interrupt resource as RF_SHAREABLE allowing uart(4) to work
    with shared IRQs in case the bus code, MD interrupt code, etc. permits.
    Together with sys/sparc64/sparc64/intr_machdep.c rev. 1.21 this fixes
    an endless loop in uart_intr() when using the second NS16550 on the ISA
    bus of sparc64 machines.
  - Destroy the hardware mutex on detach and in case attaching fails.
