Subject: [PATCH v3 0/6] VAG power control improvement for sgtl5000 codec


VAG power control is improved to fit the manual [1]. This patchset fixes as
minimum one bug: if customer muxes Headphone to Line-In right after boot,
the VAG power remains off that leads to poor sound quality from line-in.

I.e. after boot:
- Connect sound source to Line-In jack;
- Connect headphone to HP jack;
- Run following commands:
$ amixer set 'Headphone' 80%
$ amixer set 'Headphone Mux' LINE_IN

Also this series includes fixes of non-important bugs in sgtl5000 codec
driver.
