ASoC: AMD: Send correct channel for configuring DMA descriptors
Earlier, ch1 was used to define ACP-SYSMEM transfer and ch2 for ACP-I2S transfer. With recent patches ch1 is used to define channel order number 1 and ch2 as channel order number 2. Thus, Playback: ch1:SYSMEM->ACP ch2:ACP->I2S Capture: ch1:I2S->ACP ch1:ACP->SYSMEM Signed-off-by: Akshu Agrawal <akshu.agrawal@amd.com> Signed-off-by: Mark Brown <broonie@kernel.org>
