Hi,
The first patch makes composite framework support a mechanism of defering
setup transfer's data/status phase.
Second patch makes f_mass_storage use that mechanism.
Together they help the composite devices using f_mass_storage interface to
pass USBCV Mass Storage Class compliance tests.
Changes in v2:
- Review comments addressed
- Regression fix - USBCV CH-9 fails on 2nd run on composite gadget with storage
