6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jinjie Ruan <ruanjinjie@xxxxxxxxxx>
[ Upstream commit 89e362c883c65ff94b76b9862285f63545fb5274 ]
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, switch to devm_pm_runtime_enable() to fix it, so the
pm_runtime_disable() in probe error path and remove function
can be removed.
Fixes: cfdab2cd85ec ("spi: spi-geni-qcom: Set an autosuspend delay of 250 ms")
