X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0f548098af0f1a7e58e2bb9d8e1e994312c13a0f;p=openwrt%2Fstaging%2Fblogic.git

usb: dwc2: Move dwc2_readl/writel functions after hsotg structure

Moved dwc2_readl/writel functions after hsotg declaration for
adding hsotg structure to dwc2_readl/writel function prototypes.
