Douglas Anderson 8bcbde2bb1 debugfs: Document that debugfs_create functions need not be error checked
As talked about in commit b792e64021 ("drm: no need to check return
value of debugfs_create functions"), in many cases we can get away
with totally skipping checking the errors of debugfs functions. Let's
document that so people don't add new code that needlessly checks
these errors.

Probably this note could be added to a boatload of functions, but
that's a lot of duplication.  Let's just add it to the two most
frequent ones and hope people will get the idea.
