From e81b1a6e15f77858c7ade5c071e48c94fda1226f Mon Sep 17 00:00:00 2001 From: David Cohen Date: Fri, 4 Oct 2013 15:30:21 -0700 Subject: [PATCH] usb: g_ffs: fix compilation warning MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit If USB_FUNCTIONFS is selected without USB_FUNCTIONFS_ETH and USB_FUNCTIONFS_RNIS, u_ether.h won't be included and then USB_ETHERNET_MODULE_PARAMAETERS macro won't be available causing the following warning compilation: drivers/usb/gadget/g_ffs.c:81:1: warning: data definition has no type or storage class [enabled by default] drivers/usb/gadget/g_ffs.c:81:1: warning: type defaults to ‘int’ in declaration of ‘USB_ETHERNET_MODULE_PARAMETERS’ [-Wimplicit-int] drivers/usb/gadget/g_ffs.c:81:1: warning: function declaration isn’t a prototype [-Wstrict-prototypes] This patch fixes the warning by making USB_ETHERNET_MODULE_PARAMETERS to be used iff u_ether.h is included, otherwise it is not needed.
