mfd: twl-core: Improve the documentation
Saying it "returns the result" seems tautological. The read function does not return num_bytes on success, it returns zero on success. I noticed this discrepancy because some of the callers were checking for >= 0. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
