From fa9b73997cc621b9a15c96f07dda26775e61ac6a Mon Sep 17 00:00:00 2001 From: Ben Collins Date: Mon, 12 Jun 2006 18:13:42 -0400 Subject: [PATCH] ohci1394: make phys_dma parameter read-only Being able 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.
