Subject: [PATCH] clk: tegra: tegra124-emc: Fix missing put_device() call in emc_ensure_emc_driver
Date: Fri, 7 Jan 2022 08:24:36 +0000 [thread overview]
Message-ID: <20220107082436.17716-1-linmq006@gmail.com> (raw)
The reference taken by 'of_find_device_by_node()' must be released when
not needed anymore.
Add the corresponding 'put_device()' in the error handling path.
