Subject: [PATCH 2/2] driver core: platform: Drop of_device_node_put() wrapper
Date:   Thu, 11 Feb 2021 16:25:26 -0600
Message-Id: <20210211222526.1318236-3-robh@kernel.org>

of_device_node_put() is just a wrapper for of_node_put(). The platform
driver core is already polluted with of_node pointers and the only 'get'
already uses of_node_get() (though typically the get would happen in
of_device_alloc()).
