Ryan Lee	58d59d9ae5	ASoC: max98373: Changed amp shutdown register as volatile ... [ Upstream commit a23f9099ff1541f15704e96b784d3846d2a4483d ] 0x20FF(amp global enable) register was defined as non-volatile, but it is not. Overheating, overcurrent can cause amp shutdown in hardware. 'regmap_write' compare register readback value before writing to avoid same value writing. 'regmap_read' just read cache not actual hardware value for the non-volatile register. When amp is internally shutdown by some reason, next 'AMP ON' command can be ignored because regmap think amp is already ON.
