Subject[PATCH 4.8 30/57] ASoC: nau8825: fix bug in FLL parameter
Date
4.8-stable review patch.  If anyone has any objections, please let me know.

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

From: John Hsu <KCHSU0@nuvoton.com>

commit a8961cae29c38e225120c40c3340dbde2f552e60 upstream.

In the FLL parameter calculation, the FVCO should choose the maximum one.
The patch is to fix the bug about the wrong FVCO chosen.
