This adds a pr_fmt line which uses the __func__ macro. I also
convert the current pr_ lines to remove their __func__ usage.

The regulator framework uses a lot of printks with a
specific formatting using __func__. This converts them
to use pr_ calls with a central format string.

Using a separate pointer for invalid and unsupportable
doesn't save much text space and is very hard to grep.
I think it's more intelligible as:
pr_err("%s: Invalid voltage constraints\n", name);

I noticed that also, but I didn't feel like changing it when I did this.
there is another one here,
printk(KERN_WARNING "%s: could not add regulator_dev"
" load sysfs\n", __func__);
I'm not sure what this one was suppose to say.

Hi Daniel.
I think it'd be better to introduce and use:
#define rdev_err(rdev, fmt, ...)
pr_err("%s: " fmt, rdev_get_name(rdev), ##__VA_ARGS__);
#define rdev_warn(rdev, fmt, ...)
pr_warn("%s: " fmt, rdev_get_name(rdev), ##__VA_ARGS__);
#define rdev_info(rdev, fmt, ...)
pr_info("%s: " fmt, rdev_get_name(rdev), ##__VA_ARGS__);
There are some pr_<level> uses without any rdev_get_name(rdev),
but wherever an rdev is available, I'd use it.
cheers, Joe

This is some stuff from David Brownell which slipped through in review
and should be removed to just have the string. His theory is that this
allows the compiler to merge multiple versions of the format string,
resulting in a space saving but given how trivial the saving is and the
impact on legibility it's really not worth it.

That's a different thing - someone's just split the string over multiple
lines - the two strings will just be concatenated.

Don't do that, trim unneeded context from your mails. This makes it
much easier to find the actual content you've written and is much nicer
for those of us who work on mobile connections.

If you check history, you'll find I'm consistent in doing
just that, including trimming blank lines from quoted.
This was an exceptional case because quoting the original
and declaring "no additional comments" allows Daniel to
see the changes he could make in place.

I believe he's talking about the concatenated string
content itself being unintelligible gibberish.
It'd be more standard as "could not create sysfs file".

Joe, I'd be happy to take any subsequent patches you have for this.

After these patches show up in -next.
I think there were some other patches about
as well, so maybe in a week or so.
