Subject: [PATCH] clk: tegra: tegra124-emc: Fix missing put_device() call in emc_ensure_emc_driver
Git-commit: 6d6ef58c2470da85a99119f74d34216c8074b9f0
Patch-mainline: v5.18-rc1
References: git-fixes

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.

Fixes: 2db04f16b589 ("clk: tegra: Add EMC clock driver")
