Subject: [RFC PATCH 0/4] of: Automate handling of of_node_put()
Date: Sun, 17 Dec 2023 18:46:44 +0000	[thread overview]
Message-ID: <20231217184648.185236-1-jic23@kernel.org> (raw)

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

Recent addition of scope based cleanup (linux/cleanup.h) allows us
to avoid a large number of places where error handlers and early
returns have to carefully deal with left over resources.
The need to call of_node_put() on breaking out of loops over child
nodes is one of these cases and this series is to address that.

I have a similar series for property.h which I'll send out shortly
if this one sees no show stoppers.
