Checked in, with additional _U_'s for added 
freshness^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H^H^Hto squelch GCC warnings 
about unused arguments, "scsi_senddiag_pf_val" made a scalar rather 
than an array, and:

"%.*s", with an additional argument of "plen", used, just in case the 
serial number *doesn't* have its last byte 0.  ("tvb_get_string()" 
could have been used as well, although you have to assign the return 
value to a pointer, and "g_free()" the pointer when you're done.)
