Subject: usb: core: phy: add missing forward declaration for "struct device"
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9d3cd19be3e2675f5b30172f3305f79ddcb91023;p=linux.git

usb: core: phy: add missing forward declaration for "struct device"

Currently hcd.c is the only consumer of the usb_phy_roothub logic. This
already includes the required header files so struct device is known.
However, future consumers might not know about struct device.
Add a forward declaration for struct device to fix potential future
consumers which don't include any of the struct device API headers.

Fixes: 07dbff0ddbd86c ("usb: core: add a wrapper for the USB PHYs on the HCD")
