Subject: [PATCH v2 0/3] Increase the number of USB to serial devices we can
 support at once

Here's the updated patch set to increase the number of USB to serial
devices that we can support at once.

Changes from v1:
	- now only support 512 instead of 3000 devices, as that's all we
	  really need / want at this point in time.
	- removed usb_serial.minor field as it doesn't make any sense
	  now.
	- addressed review comments / issues found in first round of
	  patches.

Overall, the diffstat is still nice, we are removing more code than we
are adding:

This series is on top of my usb-linus branch of my usb.git tree on
git.kernel.org, as it relies on some patches in there already.

If there are no objections to these, I'll queue them up to be merged in
3.11.

thanks,

greg k-h
