From 64ba419b7a5acf5fc934bfad9cc46c7f17ab8026 Mon Sep 17 00:00:00 2001 From: Xenia Ragiadakou Date: Mon, 26 Aug 2013 23:29:46 +0300 Subject: [PATCH] xhci: replace USB_MAXINTERFACES with config->desc.bNumInterface This patch replaces USB_MAXINTERFACES with config->desc.bNumInterface in the termination condition for the loop that updates the LPM timeout of the endpoints on the cofiguration's interfaces, in xhci_calculate_lpm_timeout(), to avoid unnecessary loop cycles since most configurations come with 1-2 interfaces while USB_MAXINTERFACES is 32.
