From cb4c8fe57c05dbb04128503f4a7483a1163b1b47 Mon Sep 17 00:00:00 2001 From: Inaky Perez-Gonzalez Date: Fri, 25 Aug 2006 19:35:28 -0700 Subject: [PATCH] usb: deal with broken config descriptors Change usb_get_configuration() so that it is more tolerant to devices with bad configuration descriptors (it'll make it ignore configurations that fail to load).
