It doesn't cover "this".  Somthing like my patch is still necessary to
get this driver to build:

drivers/gpio/langwell_gpio.c: In function 'lnw_irq_handler':
drivers/gpio/langwell_gpio.c:210:10: error: 'struct irq_desc' has no member named 'chip'
drivers/gpio/langwell_gpio.c:211:7: error: 'struct irq_desc' has no member named 'chip'
