From 352a337832774a6929c16b569abe9cedc3db01cc Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Thu, 9 Dec 2010 22:46:29 +0100 Subject: [PATCH] USB: otg: fix link breakage, when the NOP USB Xceiver is a module If the NOP USB OTG transceiver driver is built as a module, the otg.h header declares external functions, but if they are referenced from the kernel proper, as, e.g., in the OMAP3 case, where the omap3evm board is calling the usb_nop_xceiv_register() function, linkage breaks. This patch fixes this problem.
