Subject: dma: contiguous: Export dev_get_cma_area()
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=6207948f389ec1b938a39aa43fb4aedd58d65e0d;p=thirdparty%2Fkernel%2Flinux.git

dma: contiguous: Export dev_get_cma_area()

The CMA dma-buf heap uses the dev_get_cma_area() function to retrieve
the default contiguous area.

Now that this function is no longer inlined, and since we want to turn
the CMA heap into a module, let's export it.
