Thanks, since the original patch was still in my review-hans
branch (and not yet in for-next) I've squashed this fix into
the original patch.

I've just realized there is another issue with this
("platform/x86: thinkpad_acpi: Convert btusb DMI list to quirks")

Patch, it only sets tp_features.quirks after bluetooth_init()
has already run, so the:

	if (tp_features.quirks && tp_features.quirks->btusb_bug && ...

check will never be true since tp_features.quirks is being set
too late.

I'll squash in a change moving the:

        dmi_id = dmi_first_match(fwbug_list);
        if (dmi_id)
                tp_features.quirks = dmi_id->driver_data;

to higher inside thinkpad_acpi_module_init() to fix this,
while keeping the:

#ifdef CONFIG_SUSPEND
       if (tp_features.quirks && tp_features.quirks->s2idle_bug_mmio) {
               if (!acpi_register_lps0_dev(&thinkpad_acpi_s2idle_dev_ops))
                       pr_info("Using s2idle quirk to avoid %s platform firmware bug\n",
                               (dmi_id && dmi_id->ident) ? dmi_id->ident : "");
       }
#endif

block at then end of thinkpad_acpi_module_init() so as to not change
the ordering wrt registering the lps0_dev.

Regards,

Hans
