If anyone has any objections, please let me know. ------------------ From: Hans de Goede commit 3cd2018e15b3d66d2187d92867e265f45ad79e6f upstream. Since commit d24cfee7f63d ("spi: Fix acpi deferred irq probe"), the acpi_dev_gpio_irq_get() call gets delayed till spi_probe() is called on the SPI device. If there is no driver for the SPI device then the move to spi_probe() results in acpi_dev_gpio_irq_get() never getting called. This may cause problems by leaving the GPIO pin floating because this call is responsible for setting up the GPIO pin direction and/or bias according to the values from the ACPI tables. Re-add the removed acpi_dev_gpio_irq_get() in acpi_register_spi_device() to ensure the GPIO pin is always correctly setup, while keeping the acpi_dev_gpio_irq_get() call added to spi_probe() to deal with -EPROBE_DEFER returns caused by the GPIO controller not having a driver yet.
