I don't think so. Namely during debugging the file/line info is very
useful, from my point of view. So, I think that this adding makes sense.

As I see, the goal of this patch set is overcome of checkpatch warnings.
I'd prefer not change the style of error messages in HFS/HFS+ drivers.
But this patch set makes sense because it fixes warnings of checkpatch
related to error messages.

Moreover, as I see the most of rest checkpatch's warnings makes sense
and it needs to be fixed, from my point of view.
