From 3cc1cb30735286dffba8a0675de4baaf2891aee1 Mon Sep 17 00:00:00 2001 From: Dmitry Osipenko Date: Sun, 24 Oct 2021 01:59:50 +0300 Subject: spi: tegra20-slink: Put device into suspend on driver removal pm_runtime_disable() cancels all pending power requests, while they should be completed for the Tegra SPI driver. Otherwise SPI clock won't be disabled ever again because clk refcount will become unbalanced. Enforce runtime PM suspension to put device into expected state before driver is unbound and device's RPM state is reset by driver's core.
