If anyone has any objections, please let me know. ------------------ From: Alexander Stein [ Upstream commit 90ed688792a6b7012b3e8a2f858bc3fe7454d0eb ] Drivers does cache sync during runtime resume, setting all writable registers. Not all writable registers are set in cache default, resulting in the erorr message: fsl-sai 30c30000.sai: using zero-initialized flat cache, this may cause unexpected behavior Fix this by adding missing writable register defaults.
