Subject: nouveau: add stub dma-buf mmap functionality.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e1bbc4bff928ed152a1aef2a4b80a65eccc0ce63;p=linux-beck.git

nouveau: add stub dma-buf mmap functionality.

This just adds a stub until we have some users in place to test
this with.
