6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jinjie Ruan <ruanjinjie@xxxxxxxxxx>
[ Upstream commit 67d4a70faa662df07451e83db1546d3ca0695e08 ]
It is not valid to call pm_runtime_set_suspended() for devices
with runtime PM enabled because it returns -EAGAIN if it is enabled
already and working. So, call pm_runtime_disable() before to fix it.
Fixes: d36ccd9f7ea4 ("spi: cadence: Runtime pm adaptation")
