usb: ehci: Cleanup itd/sidt_complete()

Quoted 2 lines · Suwan Kim

This patch makes itd/sitd_complete() use *bus instead of referening ehci_to_hcd(ehci)->self. And remove unnecessary "urb = NULL" lines.

That is two different things to do in the same patch, please break this up into different patches.

And when you do, say _why_ you are making these changes, not just a description of the change itself. We can read the patch to see what it does, but we do not know why you want to do this.

thanks,
