From: Jinjie Ruan <ruanjinjie@xxxxxxxxxx>

[ Upstream commit 3b577de206d52dbde9428664b6d823d35a803d75 ]

It's important to undo pm_runtime_use_autosuspend() with
pm_runtime_dont_use_autosuspend() at driver exit time unless driver
initially enabled pm_runtime with devm_pm_runtime_enable()
(which handles it for you).

Hence, call pm_runtime_dont_use_autosuspend() at driver exit time
to fix it.

Fixes: 944c01a889d9 ("spi: lpspi: enable runtime pm for lpspi")
