[PATCH] ipmi: fix uninitialized data bug
gcc issues the following warning:
drivers/char/ipmi/ipmi_si_intf.c: In function âinit_ipmi_siâ:
drivers/char/ipmi/ipmi_si_intf.c:1729: warning: âdata.irqâ 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.
