Subject: [Patch] debugfs: Remove misleading comments.

[This goes on top of Peter's symlink patch.]

From: Cornelia Huck <cornelia.huck@...ibm.com>

Just mention which error will be returned if debugfs is disabled. Callers
should be able to figure out themselves what they need to check.

Signed-off-by: Cornelia Huck <cornelia.huck@...ibm.com>
