From 1d5827a12ebd20d64b972111b846cb1ca87ff82e Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 25 Mar 2015 12:22:12 -0600 Subject: [PATCH] dm: usb: Fix type problems in usb_stor_get_info() This function assumes that unsigned long is 32-bits wide, but it is not on 64-bit machines. Use the correct type, and add a few debug() lines also.
