From b335fe681075bd6bd3e6842bad12a0ccb573dc4f Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Wed, 10 Jun 2015 17:04:04 +0200 Subject: [PATCH] usb.h: Always declare usb function prototypes There is no harm in declaring the function prototypes even if nothing implements them, and when CONFIG_DM_USB=y the various usb functions are available regardless of any controller drivers being enabled. This fixes compile warnings due to missing prototypes on ARCHs where the ARCH Kconfig always enables CONFIG_DM_USB and various usb drivers. One could argue that in the case of no controllers CONFIG_DM_USB should not be set, but this problem is typically seen during bringup of boards which do actually have usb controllers.
