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@xxxxxxxxxxxxx> http://mailman.alsa-project.org/pipermail/alsa-devel/2015-November/100962.html Thanks, Lukas Lukas Wunner (1): ALSA: hda - Use acpi_dev_present() sound/pci/hda/thinkpad_helper.c | 17 ++--------------- 1 file changed, 2 insertions(+), 15 deletions(-) -- 2.1.0 _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
