Message-Id: <1356722614-18224-4-git-send-email-geert@linux-m68k.org>
Date: Fri, 28 Dec 2012 20:23:33 +0100
From: Geert Uytterhoeven <geert@...ux-m68k.org>
To: linux-arch@...r.kernel.org,
Marek Szyprowski <m.szyprowski@...sung.com>,
linux-kernel@...r.kernel.org, linux-media@...r.kernel.org
Cc: linux-m68k@...r.kernel.org,
Geert Uytterhoeven <geert@...ux-m68k.org>
Subject: [PATCH/RFC 3/4] avr32/bfin/c6x/cris/frv/m68k/mn10300/parisc/xtensa: Add dummy get_dma_ops()
Provide dummy versions of get_dma_ops(), as dma_mmap_attrs() and
dma_get_sgtable_attrs() (will) need these
Signed-off-by: Geert Uytterhoeven <geert@...ux-m68k.org>
