Subject: [PATCH 1/8] firewire: remove an unused function argument
Date: Sun, 20 Jun 2010 22:50:35 +0200 (CEST)	[thread overview]
Message-ID: <tkrat.21cad29c23b5e375@s5r6.in-berlin.de> (raw)
In-Reply-To: <tkrat.ba0692c55cd50593@s5r6.in-berlin.de>

void (*fw_address_callback_t)(..., int speed, ...) is the speed that a
remote node chose to transmit a request to us.  In case of split
transactions, firewire-core will transmit the response at that speed.

Upper layer drivers on the other hand (firewire-net, -sbp2, firedtv, and
userspace drivers) cannot do anything useful with that speed datum,
except log it for debug purposes.  But data that is merely potentially
(not even actually) used for debug purposes does not belong into the API.
