From 5f7e2cb56af6800a4158514cc27921141e67ae19 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Fri, 14 Oct 2022 17:49:33 -0700 Subject: soc: qcom: cmd-db: Mark device as having no PM support This driver purely exposes information from memory to the kernel. Let's mark it as not having any device PM functionality, so that during suspend we skip even trying to call a suspend function on this device. This clears up suspend logs more than anything else, but it also shaves a few cycles off suspend.
