From 5311f88e07ce83ea529a6a84716cbe32e8db2b6a Mon Sep 17 00:00:00 2001 From: Tomasz Figa Date: Thu, 19 Dec 2019 18:39:54 +0900 Subject: usb: mtk-xhci: Do not explicitly set the DMA mask The mtk-xhci platform glue sets the DMA mask to 32 bits on its own, which was needed before commit fda182d80a0b ("usb: xhci: configure 32-bit DMA if the controller does not support 64-bit DMA"), but now it has no effect, because xhci_gen_setup() sets it up for us according to hardware capabilities. Remove the useless code.
