No. It's a sign that I'm using an older version of GCC than you are.
It compiles just fine on my system. :-(
I moved the function declaration into the inner block in order to _avoid_
a compiler warning! When you build the driver with your
"ohci-add-auto-stop-support-hack-hack" installed and CONFIG_PM not set,
does your compiler complain about ohci_restart being declared `static' but
never defined? Mine does.
Sigh... This deserves to be cleaned up properly, but if you don't mind
I'll put it off for a little while.
BTW, we've had equivalent code in the USB core drivers for a long time.
>From drivers/usb/core/hub.c:
if (udev->bus->b_hnp_enable || udev->bus->is_b_host) {
static int __usb_port_suspend(struct usb_device *,
int port1);
err = __usb_port_suspend(udev, udev->bus->otg_port);
if (err < 0)
dev_dbg(&udev->dev, "HNP fail, %d\n", err);
}
I assume that this hasn't bothered you because you never have
CONFIG_USB_OTG set during a build, so the compiler never sees this code.

The spaces were almost entirely the work of one rather prolific developer
(not me!) whose personal style is to always put a space between a function
name and the following open paren. Cleaning it up will be a big job...
but I suppose it could be done over a period of time.
