[alsa-devel] [PATCH 5/9] ASoC: sun8i-codec-analog: Use callbacks to add headphones and lineout outputs

[Vasily Khoruzhick]

From: Marcus Cooper <codekipper at gmail.com>

Widgets for headphones and lineout outputs on A64 are different enough
and use different regs, so move addition of these outputs into callback to
simplify upcoming A64 support.
