From 288ee3c36255d0c2d32830313f527e1474a09e9f Mon Sep 17 00:00:00 2001 From: Chunfeng Yun Date: Tue, 24 Apr 2018 10:52:46 +0800 Subject: [PATCH] usb: mtu3: avoid TX data length truncated in SS/SSP mode The variable of 'count' is declared as u8, this will cause an issue due to value truncated when works in SS or SSP mode and data length is greater than 255, so change it as u32.
