Subject: [PATCH 09/13] iio: addac: ad74413r: Use __free(fwnode_handle) to replace fwnode_handle_put() calls
Date: Sun, 14 Jan 2024 17:20:05 +0000 [thread overview]
Message-ID: <20240114172009.179893-10-jic23@kernel.org> (raw)
In-Reply-To: <20240114172009.179893-1-jic23@kernel.org>
From: Jonathan Cameron <Jonathan.Cameron@huawei.com>
This use of the new cleanup.h scope based freeing infrastructure allows
us to exit directly from error conditions within the
fwnode_for_each_available_child_node(dev, child) loop. On normal exit
from that loop no fwnode_handle reference will be held and the child
pointer will be NULL thus making the automatically run
fwnode_handle_put() a noop.
