Subject: [PATCH] media: i2c: replacing of_node_put with __free(device_node)
Date: Wed,  8 May 2024 01:42:53 -0400
Message-Id: <20240508054253.1568781-1-abdulrasaqolawani@gmail.com>

Replaced instance of of_node_put with __free(device_node)
and removed goto statement to protect against any memory leaks
due to future changes in control flow.
