From 11080bf6c705ca1ebed23417204a73738bd81669 Mon Sep 17 00:00:00 2001 From: Zeng Tao <prime.zeng@hisilicon.com> Date: Fri, 29 Jun 2018 01:54:19 +0800 Subject: [PATCH] usb: ohci: change the NUM_EDs from 8 to 32 For ohci, the maximam supported endpoint number is 32(in and out), and now we have used (usb_pipeendpoint(pipe) << 1) to index the specified endpoint descritor, usb_pipeendpoint(pipe) can reach 0xf, so we need change the NUM_EDs from 8 to 32.
