We have a device reference, utilize it instead of pr_warn().

There is at least one more hwmon to convert in applesmc.c

Perhaps a coccinelle script?

Two questions for Julia Lawall:

o is there a better way to do this than repeat the blocks
  one for each replacement
o can struct device * dev be made an arbitrary identifier

Definitely yes here; otherwise you only catch the ones named 'dev'.
Did you try "identifier dev;" ?

The type of fn is irrelevant; you don't need to specify it.

There is also the case where 'struct device *dev' is a local variable

fn(...) {
...
struct device *dev = e;
<...
...>
}

or when it isn't but is still available

fn (..., struct \(platform_device\|i2c_device\|spi_device\) *pdev, ...) {
}
