Subject: [PATCH] ASoC: mmp-sspa: Fix the error handling in probe()
Git-commit: 6ea460d52299f7febd408f2710d7c43ce505bc2c
Patch-mainline: v5.8-rc1
References: jsc#SLE-16518

If we fail after pm_runtime_enable(), we fail to undo it. Same with
clk_prepare_enable(). Let's order them after all things that can fail.

Fixes: 7d98cc648253 ("ASoC: mmp-sspa: Add support for the runtime power management")
