[PATCH] ipmi: fix uninitialized data bug
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.
