There are two reasons for this patch:
1. There are some potential requirements for ion_alloc in kernel space,
some media drivers need to allocate media buffers from ion instead of
buddy or dma framework, this is more convient and clean very for media
drivers. And In that case, ion is the only
Hi Zeng,
Thank you for the patch! Perhaps something to improve:
[auto build test WARNING on staging/staging-testing]
[also build test WARNING on v5.1-rc2 next-20190329]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system]

If we're going to export ion_alloc() for other drivers to use then let's
make an ion_free() helper function as well.
void ion_free(struct dma_buf *dmabuf)
{
dma_buf_put(dmabuf);
}
