Subject: ASoC: rsnd: tidyup DMA start/stop timing on SSI
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1ceeab2679069738fc73da6d8256014d3e195dab;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

ASoC: rsnd: tidyup DMA start/stop timing on SSI

Current DMA starts after SSI, and stops before SSI. but we need
to reverse these order. Otherwise, under/over run error might happen.
