Subject: langwell_gpio: modify EOI handling following change of kernel irq subsystem
From: Feng Tang <feng.tang@xxxxxxxxx>
Latest kernel has many changes in IRQ subsystem and its interfaces, like
adding "irq_eoi" for struct irq_chip, this patch is a follow up change for
that.
Also remove the unnecessary cast for a "void *".
