ramips: kernel: fix awake-rt305x-dwc2 patch At this point in v5.4 kernel we cannot use dwc2_readl() and dwc2_writel() since they rely on the value hsotg->needs_byte_swap which cannot be obtained before the controller wakes up. We should use readl() and writel() to wake up the controller before calling dwc2_check_core_endianness().
