i3c: master: svc: Fix pm_runtime_set_suspended() with runtime pm enabled
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. Cc: stable@vger.kernel.org # v5.17 Fixes: 05be23e ("i3c: master: svc: add runtime pm support") Reviewed-by: Frank Li <Frank.Li@nxp.com> Reviewed-by: Miquel Raynal <miquel.raynal@bootlin.com> Signed-off-by: Jinjie Ruan <ruanjinjie@huawei.com> Link: https://lore.kernel.org/r/20240930091913.2545510-1-ruanjinjie@huawei.com Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
