Perhaps while at it make this (and other similar changes in this patch):

pr_err("%s(): Unable to ...", __func__, ...);

So that it becomes more resilient against this kind of rename?

... and this seem like unrelated whitespace changes.

And the second line here also needlessly changes the indentation.
