We seem to have different conceptions of churn. Each hunk here is an
improvement for both SLOC count and usefulness of the generated error
message.

	failed to register somename: -5

is worse than

	error EIO: failed to register somename

, isn't it?

We had this disagreement already before. Yes dev_err_probe() is useful
for three reasons and this driver only benefits from two of these.
That's IMHO still one reason more than needed to justify such a change.

And if you think that a function should only be used if all advantages
are useful for the caller, let us reconsider if we really need capture
support in the pwm framework as only two of the 68 drivers make use of
it.

Best regards
Uwe
