Wei Yongjun	81a812c98b	ASoC: sprd: Fix to use list_for_each_entry_safe() when delete items ...

Wei Yongjun	7c88b92816	ASoC: sprd: Fix return value check in sprd_mcdt_probe() ... In case of error, the function devm_ioremap_resource() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().

Baolin Wang	d7bff893e0	ASoC: sprd: Add Spreadtrum multi-channel data transfer support ... On Spreadtrum platform, the audio subsystem will use the multi-channel data transfer controller to transfer sound stream between audio subsystem and other AP/CP subsystem. It can support 10 DAC channel and 10 ADC channel, and each channel has 512 bytes depth data fifo. Moreover each channel can be used DMA mode or interrupt mode to transfer data.
