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.
