Yes. However, since we need to check there is _not_ those chipsets,
it's tricky. Probably it's a following or similar code, um.. IMHO it
seems not simple enough. Idea?


static void __devinit blacklist_check()
{
has_bug = 1;
}
DECLARE_PCI_FIXUP_EARLY(blacklist);
static void __devinit graylist_check()
{
has_bug = 2;
}
DECLARE_PCI_FIXUP_EARLY(graylist);
static int __init pmtmr_bug_check()
{
if (!has_bug)
pmtmr_need_workaround = 0;
else
...
}
late_initcall(pmtmr_bug_check);
