From 6b04e47b73f2a0d2c330cecca99f8e2cb8f85b34 Mon Sep 17 00:00:00 2001 From: "tomaspaukrt@email.cz" Date: Wed, 25 Sep 2019 12:08:44 +0200 Subject: [PATCH] spi: orion: fix runtime PM initialization The current initialisation of runtime PM in the orion-spi.c driver is incorrect, because calling pm_runtime_put_autosuspend before calling pm_runtime_get leads to a negative value of the reference count and therefore it sometimes causes suspend during a transmission.
