Subject: media: it913x: init tuner on attach
From: Bimow Chen <[email protected]>
commit 01b461bbe74b89da8941f4c95711777d87b9172e upstream.
That register is needed to program very first in order to operate
correctly.
[[email protected]: returned sequence back, removed sleep, moved reg
write earlier to prevent populating tuner ops in case of failure]
