This is version two of fixing a warning message generated by GCC
  CC [M]  drivers/char/ipmi/ipmi_si_intf.o
drivers/char/ipmi/ipmi_si_intf.c: In function 'try_init_spmi':
drivers/char/ipmi/ipmi_si_intf.c:2016:8: warning: variable 'addr_space' set but not used

And also updates a broken web address.

This looks like after applying this patch 'info = ...' will be part of
if statement (without indent before 'info = ...')

	if (spmi->addr.space_id == ACPI_ADR_SPACE_SYSTEM_MEMORY)
		info = kzalloc(sizeof(*info), GFP_KERNEL);

It's correct?

Thanks

the original patch I dont think this is correct. a bit confusing with 
the if(!info) at the bottom of this.
here's an updated version if it looks to be correct I'll resend if not 
I'll redu:

Sorry, but I think that new patch is not correct.

Why do you delete this row "info = kzalloc(sizeof(*info), GFP_KERNEL)"?
There is the only one unused variable `addr_space`, so I think it should
be removed, that's all.

The following code is correct and not need to be changed:

	info = kzalloc(sizeof(*info), GFP_KERNEL);
	if (!info) {
		printk(KERN_ERR PFX "Could not allocate SI data (3)\n");

Please see below my patch.
Thanks.

Well, Sergey sent a patch, but I don't think it was quite in a form that 
can be taken.  Do you want to resend per the standard rules?
