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, ...) {
}
$ cat dev_printk.cocci
