Hello Linus,
Please pull to receive the dmaengine updates for v5.6-rc1. This time we
have a bunch of core changes to support dynamic channels, hotplug of
controllers, new apis for metadata ops etc along with new drivers for
Intel data accelerators, TI K3 UDMA, PLX DMA engine and hisilicon
Kunpeng DMA engine. Also usual assorted updates to drivers.
The following changes since commit e42617b825f8073569da76dc4510bfa019b1c35a:
Linux 5.5-rc1 (2019-12-08 14:57:55 -0800)

This broke the docs build for me with:
Sphinx parallel build error:
docutils.utils.SystemMessage: /linux/Documentation/driver-api/dmaengine/client.rst:155: (SEVERE/4) Unexpected section title.
Optional: per descriptor metadata
---------------------------------
The patch below fixes the build. It may not produce the output you
intended, it just makes it bold rather than a heading, but it doesn't
really make sense to have a heading inside a numbered list.

Can I suggest, in future, 'make W=1'. That will run the kernel-doc
script which would presumably have caught this problem. If we get all
the existing doc errors cleaned up, we can promote that to be run as
part of the standard build, but until then we don't want to dump 700
new errors on everybody.
