From ea9733ac4c268cc862ec1e414f066f192348ef5a Mon Sep 17 00:00:00 2001 From: qianfan Zhao Date: Tue, 16 Nov 2021 08:30:12 +0800 Subject: [PATCH] drivers: musb_gadget: Save endpoint desc to usb_ep->desc Fix fastboot flash bug. If the downloading file size is equal to the partition size, "fastboot flash" can't work, at least in sunxi platform, because used an uninitalized point: ep->desc. This patch also fixed 'data abort' bug in am335x platform. Reproduce: fastboot flash loader1 spl/sunxi-spl.bin.
