During this conversion, the functionality of the V7 wrapper hasn't been tested yet. This will be done in a separate CL that will also include required updates to the VTS tests. Since the changes were made to the code shared with pre-V7 versions, verified that V6 HAL didn't regress. Bug: 142480271 Test: atest VtsHalAudioEffectV6_0TargetTest Test: m VtsHalAudioEffectV7_0TargetTest Test: m android.hardware.audio@7.0-service.example Change-Id: I72389c8d564596bef22b47dfdcb2e77d636ef0a3 Merged-In: I72389c8d564596bef22b47dfdcb2e77d636ef0a3
