Subject: [PATCH] soc: qcom: ocmem: Fix missing put_device() call in of_get_ocmem
Git-commit: 0ff027027e05a866491bbb53494f0e2a61354c85
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: 01f937ffc468 ("soc: qcom: ocmem: don't return NULL in of_get_ocmem")
