From 643de6240b0b59c420ad71dfeeb3125a3607af92 Mon Sep 17 00:00:00 2001 From: Michal Nazarewicz Date: Thu, 14 Apr 2011 17:47:09 +0200 Subject: usb: core: Change usb_create_sysfs_intf_files()' return type to void The usb_create_sysfs_intf_files() function always returned zero even if it failed to create sysfs fails. Since this is a desired behaviour there is no need to return return code at all. This commit changes function's return type (form int) to void.
