+Subject: usb: don't create dma pools for HCDs with a localmem_pool
+Origin: https://git.kernel.org/linus/dd3ecf17ba70a70d2c9ef9ba725281b84f8eef12
+
+If the HCD provides a localmem pool we will never use the DMA pools, so
+don't create them.
+
+Fixes: b0310c2f09bb ("USB: use genalloc for USB HCs with local memory")
