From 9a35f8767a568bdbb21ba7c3276fdc5321e3960d Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Sun, 2 Oct 2011 16:45:47 +0200 Subject: [PATCH] usb: musb: allow building USB_MUSB_TUSB6010 as a module Commit 1376d92f9 "usb: musb: allow musb and glue layers to be modules" made the USB_MUSB_TUSB6010 option modular, but actually building the driver as a module does not work, so various randconfig builds actually fail. This changes all code that depends on the option to also check for modular builds, and exports the necessary symbols.
