[dpdk-stable] patch 'doc: reduce indentation in meson build file' has been queued to stable release 19.11.1

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 19.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/13/20. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Thanks.

Luca Boccassi

Subject: [PATCH] doc: reduce indentation in meson build file

[ upstream commit bbfc94efcafab236339cd1ec73bb523275d52c60 ]

When building the API docs, we can make the meson.build file easier to
read, and allow more code per line, by using subdir_done() to quit early.
