First of all, what's wrong with the pattern used in the kernel when we
explicitly show the compound literal? Also we put a space before {.

Second, can't it all be hidden in the GPIOLIB just by passing the pointer to
the above initialised structure? Yes, it will take a pointer space in GPIO chip
for all, but I think it will reduce the burden.
