If I don't need that intermediate variable, then my previous patch containing

cs8900_interrupt(LPC22xx_INTERRUPT_EINT2, cs);

,should be correct right ?
No, because here you have now the wrong function type. What you need is
this:
static void cs8900_isr(void *arg)
{
cs8900_interrupt(LPC22xx_INTERRUPT_EINT2, arg);
}
I followed the flow of bsp_interrupt_handler_dispatch() & where it leads, but
couldn't figure out much. Will try again tomorrow.
I still don't understand what mistake I'm doing regarding removing superfluous
entities from the code. :-(
You should take the time to understand how the generic interrupt
framework works. You can compile for example the realview_pbx_a9_qemu
BSP and run it on Qemu. Set a break point to
bsp_interrupt_handler_dispatch() and see what happens if you single step
with the debugger though it.
