Re: [git pull] PCI fixes

+	/* Configuration request Retry Status */

+		goto wait;

I think this works only when CRS Software Visibility is enabled,
isn't it? Currently there is no code to enable CRS Software
Visibility. And there can be root ports that doesn't support CRS
Software Visibility. We need consideration about this.

+	mdelay(100);
+	delay -= 100;
+	if (delay > 0)
+		goto again;

We must use msleep() instead of mdelay().
