Subject: usb: gadget: f_sourcesink: Fix isoc transfer for USB_SPEED_SUPER_PLUS
From: Pavankumar Kondeti <quic_pkondeti@xxxxxxxxxxx>
commit 904edf8aeb459697129be5fde847e2a502f41fd9 upstream.
Currently when gadget enumerates in super speed plus, the isoc
endpoint request buffer size is not calculated correctly. Fix
this by checking the gadget speed against USB_SPEED_SUPER_PLUS
and update the request buffer size.
Fixes: 90c4d05780d4 ("usb: fix various gadgets null ptr deref on 10gbps cabling.")
