From 27980463256060aaef8db0ddfcf40fd2342b96e8 Mon Sep 17 00:00:00 2001 From: Pavankumar Kondeti Date: Sat, 22 Jan 2022 08:33:22 +0530 Subject: [PATCH] usb: gadget: f_sourcesink: Fix isoc transfer for USB_SPEED_SUPER_PLUS 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.")
