I think a more idiomatic way to write this would be:

static int
calculate_tsensor_calibration(const struct tegra_tsensor *sensor,
			      struct tsensor_shared_calibration shared,
			      u32 *calib)

If I do that, it will go over the 80 character limit by quite a few
characters, which is why I didn't use that style. Personally I'm fine with
either style.

The above doesn't exceed the 80 character limit. Putting the return
value and the static keyword on a separate line is a pretty common way
to reduce line length.

Good point, I didn't think of doing that. I usually never use the above 
style, but clearly here it is the best choice.

While at it, perhaps make shared a const * instead of passing it in by
value?

That is possible, but I'm not sure what the difference would be. Is there a
style rule forbidding by-value compound types? (Also if I change the style,
it would go over 80 characters by even more.)

No it doesn't. The below fits within 80 characters per line just fine:

static int
calculate_tsensor_calibration(const struct tegra_tsensor *sensor,
			      const struct tsensor_shared_calibration *shared,
			      u32 *calib)
