From 989561de9b5112999475b406557d9c7e9e59c041 Mon Sep 17 00:00:00 2001 From: Tomeu Vizoso Date: Thu, 7 Jan 2016 16:46:13 +0100 Subject: PM / Domains: add setter for dev.pm_domain Adds a function that sets the pointer to dev_pm_domain in struct device and that warns if the device has already finished probing. The reason why we want to enforce that is because in the general case that can cause problems and also that we can simplify code quite a bit if we can always assume that. This patch also changes all current code that directly sets the dev.pm_domain pointer. Signed-off-by: Tomeu Vizoso Reviewed-by: Ulf Hansson Signed-off-by: Rafael J.
