The TQMa6UL board uses the gpio-keys driver with GPIOs provided by a PCA9554 I2C GPIO expander. This currently doesn't work as the GPIOs are read in a poller during an ongoing I2C transfer on the same bus. This series fixes that by adding a slice to struct gpio_chip and checking its availability before using it.
