Subject: [PATCH 2.6.17-rc5-mm2 13/18] ohci1394: make phys_dma parameter read-only
Date: Fri, 2 Jun 2006 22:20:17 +0200 (CEST) [thread overview]
Message-ID: <tkrat.4daedad8356d5ae7@s5r6.in-berlin.de> (raw)
In-Reply-To: <tkrat.39c0a660f27b4e91@s5r6.in-berlin.de>
Ability to switch physical DMA on and off at run time would be a nice
feature but a PITA to support by highlevel drivers and userspace apps.
Therefore allow it only to be set when the driver is being loaded.
