The driver was allocating memory for storing GPIOs for external control
with unnecessary GFP_ZERO flag. Then right after allocation it
initialized memory to -EINVAL in loop. Skip the GFP_ZERO flag.

Applied, though it's a bit of a microptimisation and it would be better
to use kmalloc_array() instead.
