[PATCH 0/7] USB: cdc: add control and state defines

Several drivers use the control-line and serial-state bitmap values from
the CDC spec, but there were no matching defines in the global CDC
(UAPI) header.

This series adds the missing defines and converts cdc-acm and f_acm to
use them.

One staging driver also had an unused set of CDC defines which are
removed.

The final patch by Yan Xinyu, which triggered this work, converts the
usb_wwan driver to use CDC defines instead of hardcoded values in its
line-control handling.

Greg, are you ok with me taking these through USB serial (where there
are a few more drivers that could potentially use them) or do you want
to take the lot through your tree directly?
