Subject: [media] au0828: move the code that sets DTV on a separate function
X-Git-Tag: firefly_0821_release~176^2~2474^2~939
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=164352023104207322614deef8d03bd0d773a22a;p=firefly-linux-kernel-4.4.55.git

[media] au0828: move the code that sets DTV on a separate function

As we'll be adding a code to resume tuner operation, we
need to move the code that actually sets DTV on a separate
function, to be called by the resume code.

No functional changes, just code got moved.
