We leak "cd" if the cd->xfer_buf allocation fails. It was weird to
"goto error_gpio_irq" so I changed the label name. (Label names should
reflect the label location not the goto location otherwise you get an
"all roads lead to Rome problem").

If "cd" were NULL then we would dereference it when we print the error
message. Fortunately enough, it can't ever be NULL so we can remove
those lines.

"*max" is a size_t (long) type but "1" is an int so static checkers
complain that the shift could wrap.
