Mark writes: ASoC/extcon: arizona: Fix interaction between HPDET and headphone outputs This patch series covers both ASoC and extcon subsystems and fixes an interaction between the HPDET function and the headphone outputs - we really shouldn't run HPDET while the headphone is active. The first patch is a refactoring to make the extcon side easier.
