This fixes pcs_request_gpio() in the pinctrl-single driver when

One line?
One line is more important that wrapping to 75 chars?
+ byte_num = (pcs->bits_per_pin * pin) / BITS_PER_BYTE;

Sounds like playing around pretty well defined macro and functions,
e.g. DIV_ROUND_UP(), round_up().
I admit, I just copied existing code (which may be a reason to leave this the
way it is). But, I only see once place to do this:
offset = round_down(byte_num, mux_bytes);
Did I miss another?
