staging: android: ion: Fix dma direction for dma_sync_sg_for_cpu/device (d6b246bb) · Commits · e / devices / android_kernel_fairphone_FP4

Use the direction argument passed into begin_cpu_access and end_cpu_access when calling the dma_sync_sg_for_cpu/device. The actual cache primitive called depends on the direction passed in. Signed-off-by:
