If anyone has any objections, please let me know. ------------------ From: Linus Walleij [ Upstream commit c2c0b67dca3cb3b3cea0dd60075a1c5ba77e2fcd ] The tas2781-i2c driver gets an IRQ from either ACPI or device tree, then proceeds to check if the IRQ has a corresponding GPIO and in case it does enforce the GPIO as input and set a label on it. This is abuse of the API: - First we cannot guarantee that the numberspaces of the GPIOs and the IRQs are the same, i.e that an IRQ number corresponds to a GPIO number like that. - Second, GPIO chips and IRQ chips should be treated as orthogonal APIs, the irqchip needs to ascertain that the backing GPIO line is set to input etc just using the irqchip. - Third it is using the legacy API which should not be used in new code yet this was added just a year ago. Delete the offending code. If this creates problems the GPIO and irqchip maintainers can help to fix the issues. It *should* not create any problems, because the irq isn't used anywhere in the driver, it's just obtained and then left unused.
