From 7c18e3c6b309aebc0fde38bda5ff30ea22c8a56c Mon Sep 17 00:00:00 2001 From: Martin Kaiser Date: Sun, 12 Nov 2023 17:52:41 +0100 Subject: hwrng: virtio - remove #ifdef guards for PM functions Use pm_sleep_ptr for the freeze and restore functions instead of putting them under #ifdef CONFIG_PM_SLEEP. The resulting code is slightly simpler. pm_sleep_ptr lets the compiler see the functions but also allows removing them as unused code if !CONFIG_PM_SLEEP.
