Hi,
These patches are a proposal to add gadget quirks in an immediate objective to adapt f_fs when using DWC3 controller. But the quirk solution is generic and can be used by other controllers to adapt gadget functions to their non-standard restrictions.
This change is necessary to make Android's adbd service to work on Intel Merrifield with f_fs instead of out-of-tree android gadget.
This new patch set was tested and validated in my environment: - Intel Merrifield was able to use DWC3/f_fs with adbd service (it wasn't before).
Changes from v45 to v6: - Updated patches from Michal Nazarewicz to address comments from Alan Stern and mine. - Modified patch 5/5 to apply request->length's pad internally to DWC3.

Michal Nazarewicz (2): usb: gadget: f_fs: remove loop from I/O function check quirk to pad epout buf size when not aligned to maxpacketsize
