From 29cc88979a8818cd8c5019426e945aed118b400e Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Tue, 23 Aug 2011 03:12:03 -0700 Subject: USB: use usb_endpoint_maxp() instead of le16_to_cpu() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Now ${LINUX}/drivers/usb/* can use usb_endpoint_maxp(desc) to get maximum packet size instead of le16_to_cpu(desc->wMaxPacketSize).
