Subject: dmaengine: pxa_dma: don't use config direction parameter
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0e95fb9ceb82433f4f910d1cece0f4d6b0c25c51;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

dmaengine: pxa_dma: don't use config direction parameter

Don't use the direction passed in the configuration, and rely on each
transfer's direction to prepare the transfers. This will enable
future removal of direction parameter from dma_slave_config.
