media: dvb-frontends: lgdt3306a.c: remove dead code
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 function altogether. The lgdt3306a_spectral_inversion function was dropped completely since the function doesn't do anything. A comment was left at its calling site to let others know that spectral_inversion defaults already set for VSB and QAM Found using - Coccinelle (http://coccinelle.lip6.fr) Link: https://lore.kernel.org/linux-media/20200903131311.442255-1-dwlsalmeida@gmail.com Signed-off-by: Daniel W.
