6.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dan Williams <dan.j.williams@xxxxxxxxx>
commit 7ff6c798eca05e4a9dcb80163cb454d7787a4bc3 upstream.
The platform driver conversion of EINJ mistakenly used
platform_device_del() to unwind platform_device_register_full() at
module exit. This leads to a small leak of one 'struct platform_device'
instance per module load/unload cycle. Switch to
platform_device_unregister() which performs both device_del() and final
put_device().
