From fc5f80b152896c1ffded2a91d11dcb08ffcffebb Mon Sep 17 00:00:00 2001 From: Chris Boot Date: Wed, 1 Feb 2012 22:36:02 +0000 Subject: firewire: Move fw_card kref functions into linux/firewire.h When writing a firewire driver that doesn't deal with struct fw_device objects (e.g. it only publishes FireWire units and doesn't subscribe to them), you likely need to keep referenced to struct fw_card objects so that you can send messages to other nodes. This patch moves fw_card_put(), fw_card_get() and fw_card_release() into the public include/linux/firewire.h header instead of drivers/firewire/core.h, and adds EXPORT_SYMBOL_GPL(fw_card_release). The firewire-sbp-target module requires these so it can keep a reference to the fw_card object in order that it can fetch ORBs to execute and read/write related data and status information.
