"placed substantially to the right" doesn't imply right-aligned. My
understanding is that it should be indented enough to make it stand
apart. I don't recall ever seeing right-aligned code.

And regarding tabs, you should be indenting using tabs as far as
possible and use spaces for the final alignment, so:

static void pwm_samsung_set_divisor(struct samsung_pwm_chip *pwm,
				    unsigned int channel, u8 divisor)

In case your emailer doesn't highlight it, that's four tabs and four
spaces.
