Another patch from Feng Tang already covers this and picked up by Andrew Morton.

[patch 04/23] langwell_gpio: modify EOI handling following change of kernel irq subsystem

Thanks,

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'
