mISDN: remove DSP_NEVER_DEFINED and adjust code identation
Browse files Browse the repository at this point in the history
The DSP_NEVER_DEFINED #ifdef is confusing, it slips in an
extra } which is not required because the previous code is
indented incorrectly.  Correct the identation and remove the
extraneous DSP_NEVER_DEFINED
