This function is supposed to return zero on success or negative error
codes on error. Unfortunately, there is a bug so it sometimes returns
non-zero, positive numbers on success.
I noticed this bug during review and I can't test it. It does appear
that the return is sometimes propogated back to _regmap_read() where all
non-zero returns are treated as failure so this may affect run time.
