Subject: [PATCH] ASoC: SOF: pci: mark last_busy value at runtime PM init
Git-commit: f1b1b9b136827915624136624ff54aba5890a15b
Patch-mainline: v5.4-rc1
References: jsc#SLE-16518 bnc#1151927 5.3.4

If last_busy value is not set at runtime PM enable, the device will be
suspend immediately after usage counter is 0. Set the last_busy value to
make sure delay is working at first boot up.
