Subject: [media] lgdt3306a: remove 20*50 msec unnecessary timeout
Author: Abylay Ospan <aos...@netup.ru>
Date: Mon Jul 25 15:38:59 2016 -0300
inside lgdt3306a_search we reading demod status 20 times with 50 msec sleep
after each read.
This gives us more than 1 sec of delay. Removing this delay should not affect
demod functionality.
