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.
