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?
