Subject: [PATCH] mISDN: remove DSP_NEVER_DEFINED and adjust code identation
From: Colin Ian King <colin.king@...onical.com>
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
