    Subject[PATCH 3.16 319/357] media: it913x: init tuner on attach
    Date
    3.16-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Bimow Chen <Bimow.Chen@ite.com.tw>

    commit 01b461bbe74b89da8941f4c95711777d87b9172e upstream.

    That register is needed to program very first in order to operate
    correctly.

    [crope@iki.fi: returned sequence back, removed sleep, moved reg
    write earlier to prevent populating tuner ops in case of failure]
