Part of this broken ACPI code is that sometimes these boards have _AEI ACPI GPIO event handlers which are broken. So far this has been dealt with in the platform/x86/x86-android-tablets.c module by it calling acpi_gpiochip_free_interrupts() on gpiochip-s with troublesome handlers to disable the handlers. But this is racy and sometimes too late. This series adds a new acpi_quirk_skip_gpio_event_handlers() function to drivers/acpi/x86/utils.c using the existing DMI table for this to avoid duplication of DMI matches. Patch 2 adds a new x86 Android tablet model which needs the new SKIP_GPIO_EVENT_HANDLERS quirk. Patch 3 uses acpi_quirk_skip_gpio_event_handlers() in axp288_charger.c to deal with there not being a ACPI event handler to disable charging from Vbus before enable 5V boost output on the tablets micro-USB conn. Sebastian (sre), since patch 3 depends on patch 1, it is probably easiest to just merge the entire series through the linux-pm tree. May we have your ack for this ?
