From 7bd4b20c876e5f7aa8e1405657aee9078f896d26 Mon Sep 17 00:00:00 2001 From: Paul Chavent Date: Sat, 12 Jan 2008 15:23:17 +0100 Subject: [PATCH] USB: usbserial: provide ezusb functions for an external module. When building an external module, the ezusb_* functions are not defined if we haven't loaded any built'in module that use them (whiteheat, keyspan, ...). This patch allow to build those functions even if we only have selected the usbserial generic driver.
