Subject: [media] lgdt3306a: remove 20*50 msec unnecessary timeout
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=dd14523a8e5cf618862dcfa6635297c65f0e26ee;p=linux-beck.git

[media] lgdt3306a: remove 20*50 msec unnecessary timeout

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.
