Subject: [PATCH 14/20] media: dvb-frontends: lgdt3306a.c: remove dead code

From: "Daniel W. S. Almeida" <dwlsalmeida@...il.com>

Fix the following coccinelle report:

drivers/media/dvb-frontends/lgdt3306a.c:718:5-8:
Unneeded variable: "ret". Return "0" on line 744

Code was enclosed with #if 0 and thus this variable was not needed.
Remove that code altogether.

Found using - Coccinelle (http://coccinelle.lip6.fr)
