gcc issues the following warning:

drivers/char/ipmi/ipmi_si_intf.c: In function ‘init_ipmi_si’:
drivers/char/ipmi/ipmi_si_intf.c:1729: warning: ‘data.irq’ may be used uninitialized in this function

This is indeed a bug.  data.irq is completely uninitialized in some code
paths.  Worse than that, data from a previous decode_dmi() run can easily
leak through successive calls.
