Generate with ./newHal.sh 5.0 + some typo fix in the .hal + some clang-tidy run This new HAL is an exact copy of the V5. It will be modified in following patches while R is developed. Test: push V6 to device and check audio works fine Bug: 134940862 Change-Id: Ic25d30175032e76e0d3208fb876451de9ae6b7b4 Merged-In: Ic25d30175032e76e0d3208fb876451de9ae6b7b4 Signed-off-by: Kevin Rocard <krocard@google.com>
