If anyone has any objections, please let us know. ------------------ From: Vitaly Bordug commit ba0fc709e197415aadd46b9ec208dc4abaa21edd upstream There is dma_mask in of_device upon of_platform_device_create() but we don't actually set coherent_dma_mask. This may cause weird behavior of USB subsystem using of_device USB host drivers.
