If anyone has any objections, please let me know. ------------------ From: Edson Juliano Drosdeck [ Upstream commit 1bc40efdaf4a0ccfdb10a1c8e4b458f4764e8e5f ] Add a quirk mechanism to allow specifying that active-high jack-detection should be used on platforms where this info is not available in devicetree. And add an entry for the Positivo CW14Q01P-V2 to the DMI table, so that jack-detection will work properly on this laptop.
