If anyone has any objections, please let me know. ------------------ From: Chen-Yu Tsai [ Upstream commit 533275a4b5240a2bf2c592bd4536560388306d26 ] The DMA bounce buffer is attached to the PCIe host controller, i.e. all PCIe DMA transfers should use it. Move it from the PCIe (WiFi) device node down to the PCIe host controller node.
