Hmm... it seems that there are still several drivers still relying on the functions declared at: omap-dma.h: $ grep extern include/linux/omap-dma.h |perl -ne 'print "$1\n" if (m/extern\s\S+\s(.*)\(/)' >funcs && git grep -f funcs -l arch/arm/mach-omap1/pm.c arch/arm/mach-omap2/pm24xx.c arch/arm/plat-omap/dma.c drivers/dma/omap-dma.c drivers/media/platform/omap/omap_vout_vrfb.c drivers/media/platform/omap3isp/isphist.c drivers/media/platform/soc_camera/omap1_camera.c drivers/mtd/onenand/omap2.c drivers/usb/gadget/udc/omap_udc.c drivers/usb/musb/tusb6010_omap.c drivers/video/fbdev/omap/omapfb_main.c include/linux/omap-dma.h Perhaps we can remove the header and mark all the above as BROKEN. If nobody fixes, we can strip all of them from the Kernel.
