Subject: [RFC/PATCH 0/2] patchset to workaround f_fs for DWC3

Hi,

These patches are a proposal to workaround f_fs when using DWC3 controller.
Since DWC3 requires epout buffer size to be aligned to maxpacketsize, f_fs
needs to pad buffer size to match the above case.

This change is necessary to make Android's adbd service to work with f_fs
instead of out-of-tree android gadget. If this same situation is happening in
other still untested places, a more generic solution may be required.
