From 693c301a3aab4f7001f26f1006437932fa19a53b Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Tue, 30 Jan 2024 13:39:51 +0100 Subject: media: venus: Convert to dev_pm_domain_attach|detach_list() for vcodec Let's avoid some of the boilerplate code to manage the vcodec PM domains, by converting into using dev_pm_domain_attach|detach_list().
