get_dma_buf(9) convenience wrapper for get_file.

SYNOPSIS

void get_dma_buf(struct dma_buf * dmabuf);

ARGUMENTS

dmabuf

[in] pointer to dma_buf

DESCRIPTION

Increments the reference count on the dma-buf, needed in case of drivers that either need to create additional references to the dmabuf on the kernel side. For example, an exporter that needs to keep a dmabuf ptr so that subsequent exports don't create a new dmabuf.
