From b0fca50f5a94a268ed02cfddf44448051ed9343f Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Thu, 12 Aug 2010 17:43:53 +0200 Subject: usb gadget: don't save bind callback in struct usb_gadget_driver MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit To accomplish this the function to register a gadget driver takes the bind function as a second argument. To make things clearer rename the function to resemble platform_driver_probe. This fixes many section mismatches like WARNING: drivers/usb/gadget/g_printer.o(.data+0xc): Section mismatch in reference from the variable printer_driver to the function .init.text:printer_bind() The variable printer_driver references the function __init printer_bind() All callers are fixed.
