From d5bb9b81dbfa35d117ecb58022ee6e7e41e4772d Mon Sep 17 00:00:00 2001 From: Robert Baldyga Date: Mon, 4 May 2015 14:55:13 +0200 Subject: usb: composite: add bind_deactivated flag to usb_function This patch introduces 'bind_deactivated' flag in struct usb_function. Functions which don't want to be activated automatically after bind should set this flag, and when they start to be ready to work they should call usb_function_activate(). When USB function sets 'bind_deactivated' flag, initial deactivation counter is incremented automatically, so there is no need to call usb_function_deactivate() in function bind.
