Thread: [Linux-mips-commits] CVS: linux/arch/mips/au1000/common dma.c,1.1,1.2 usbdev.c,1.1,1.2

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Update of /cvsroot/linux-mips/linux/arch/mips/au1000/common
In directory usw-pr-cvs1:/tmp/cvs-serv24086/arch/mips/au1000/common

Modified Files:
	dma.c usbdev.c 
Log Message:
Renamed the Au1000 dma functions to not collide with kernel/dma.c.
Also, /proc/dma will show the output from kernel/dma.c:get_dma_list(),
not the Au1000 dma list. To fix requires a change to fs/proc/proc_misc.c.
