Subject: [PATCH 00/12] drm: add check if io_mem_pfn is NULL and cleanup

I found an OOPS when I used the mainline kernel for graphical tests in Hisilicon
D05, I do not know how to solve this problem until I saw your discussion on this
issue a month ago:

https://lists.freedesktop.org/archives/dri-devel/2017-November/159046.html

And my problem can be solved perfectly by your solution.

This is important for me, I want to solve this problem as soon as possible. So
I follow the result of your discussion, make and send these patches below.

If anything is not good, please point it out, thanks.

  drm/ttm: Use ttm_bo_default_io_mem_pfn if io_mem_pfn is NULL
