[PATCH v2 0/3] USB: gadget: f_hid: Add Feature reports

[Vicki Pfau <vi@endrift.com>]

This patchset adds support for Set- and Get-Feature report handling in
the f_hid gadget subsystem.

Following up on a patchset from mid-2022[1] which stalled out due in
part to neither Maxim Devaev nor I properly testing the interaction with
the use_out_ep feature he added at some point, I've revised it based on
Greg's original feedback.

Unfortuantely, it was never quite clear to me how to properly test this
patchset per Maxim's concerns, so I was hoping to resubmit it with
Greg's feedback addressed and see if Maxim is able to test it now.

Note also that this is based on my original patchset, not the revised
version submitted by David Sands[2] at a later point. He may have some
opinions that would make sense to address before anything exposed to
usermode lands.
