(org-mode-p) does the advertized job: checking whether we are in
org-mode major mode.  It would be confusing to also check against 
org derived modes, at least with that function's name.

Fixed, I corrected this directly in `org-edit-src-code', allow source
code to be edited from org-mode derived modes.

Can you share what kind of derived mode you're writing?  What for?
