Hi,

It's probably a bug fix that unveils the link errors.

commit: 420520766a796d36076111139ba1e4fb1aadeadd [media] media: Kconfig: add 
dependency of HAS_DMA
date:   in the future
config: m32r-allyesconfig (attached as .config)
compiler: m32r-linux-gcc (GCC) 4.9.0
reproduce:
         wget 
https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross
 -O ~/bin/make.cross
         chmod +x ~/bin/make.cross
         git checkout 420520766a796d36076111139ba1e4fb1aadeadd
         # save the attached .config to linux build tree
         make.cross ARCH=m32r

Thanks, i will reproduce this tonight and see. But just fyi, i am no
longer using my su...@vectorindia.org because of a change in dayjob.
I would have missed this mail unless the date of the mail was showing
as Jan 10, 2002.

Before this patch m32r allyesconfig used to fail with the error:
../drivers/media/v4l2-core/videobuf2-dma-contig.c: In function 'vb2_dc_get_userptr': ../drivers/media/v4l2-core/videobuf2-dma-contig.c:484:28: error: implicit declaration of function 'dma_get_cache_alignment' [-Werror=implicit-function-declaration]
  unsigned long dma_align = dma_get_cache_alignment();

and build never went past this point. This concerned patch fixed the error and brought out new errors which were never known before this patch.

Regards
Sudip
