linux-next: manual merge of the drm tree with Linus' tree

From: Stephen Rothwell
Date: Sun Aug 25 2019 - 23:13:03 EST


Hi all,

Today's linux-next merge of the drm tree got a conflict in:

drivers/gpu/drm/mediatek/mtk_drm_drv.c

between commit:

7837951a12fd ("drm/mediatek: include dma-mapping header")

from Linus' tree and commit:

9aef5867c86c ("drm/mediatek: drop use of drmP.h")

from the drm tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging. You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
