[PATCH] media: fix a typo CONFIG_HAVE_GENERIC_DMA_COHERENT in videobuf2-dma-contig.c

[Prabhakar Lad]

From: Lad, Prabhakar <prabhakar.lad@ti.com>

from commit 93049b9368a2e257ace66252ab2cc066f3399cad, which adds
a check HAVE_GENERIC_DMA_COHERENT for dma ops, the check was wrongly
made it should have been HAVE_GENERIC_DMA_COHERENT but it was
CONFIG_HAVE_GENERIC_DMA_COHERENT.
This patch fixes the typo, which was causing following build error:

videobuf2-dma-contig.c:743: error: 'vb2_dc_get_dmabuf' undeclared here (not in a function)
make[3]: *** [drivers/media/v4l2-core/videobuf2-dma-contig.o] Error 1

[Kyungmin Park]

Hi,

Does it right to use CONFIG_HAVE_GENERIC_DMA_COHERENT?
it defined at init/Kconfig

config HAVE_GENERIC_DMA_COHERENT
        bool
        default n
and use at C file or header file as CONFIG_ prefix?
e.g., include/asm-generic/dma-coherent.h:#ifdef CONFIG_HAVE_GENERIC_DMA_COHERENT

Thank you,
Kyungmin Park

The CONFIG_HAVE_GENERIC_DMA_COHERENT based patch was a quick workaround
for the build problem in linux-next and should be reverted now. The
correct patch has been posted for drivers/base/dma-mapping.c to LKML,
see http://www.spinics.net/lists/linux-next/msg22890.html

I was referring to this patch from Mauro,
http://git.linuxtv.org/media_tree.git/commitdiff/93049b9368a2e257ace66252ab2cc066f3399cad
which introduced this build error.
