Hi Takashi,
the acpi_dev_present() API has now landed in Linus' tree. Thus, after Linus' tree gets merged back into yours, it would be possible to use the API in the Thinkpad hda drivers as per the following patch.
I've also pushed it to GitHub in case anyone prefers perusing it in a browser: https://github.com/l1k/linux/commit/a1473d726b57eaf97c4de8812c5967603068e261
An ack for this patch was kindly provided by Hui Wang with: Message-ID: 5653C291.9090607@canonical.com http://mailman.alsa-project.org/pipermail/alsa-devel/2015-November/100962.ht...
A back merge is ugly and I'd like to avoid it. This is no urgent fix but rather a cleanup, right? If so, I'd postpone this to 4.6.
I've noticed this patch isn't in one of your trees, so it looks like it's not queued for 4.6 yet. If there are objections against it please let me know. If there aren't, I'd like to gently remind of the patch's existence.
Sorry for the delay, it's merged now.
heads-up: we've identified that the ACPI subsystem reports devices as present even if they are explicitly disabled in the BIOS _STA routine. we have a couple of WIP patches to work around this issue that is blocking for some CHT-T devices, and they pretty much amount to a revert and addition of an explicit presence test -Pierre
