From c8a25900f35e575938c791507894c036c0f2ca7d Mon Sep 17 00:00:00 2001 From: Stefan Richter Date: Tue, 10 Mar 2009 20:59:16 +0100 Subject: firewire: cdev: amendment to "add ioctl to query maximum transmission speed" The as yet unreleased FW_CDEV_IOC_GET_SPEED ioctl puts only a single integer into the parameter buffer. We can use ioctl()'s return value instead. (Also: Some whitespace change in firewire-cdev.h.)
