PM: runtime: Introduce one more usage counter guard

rafaeljw · rafaeljw · commit 384b52ce3211 · 2025-10-03T21:09:54.000+02:00
Follow previous commit 9a0abc3 ("PM: runtime: Add auto-cleanup macros for "resume and get" operations") and define a runtime PM usage counter guard in which pm_runtime_get_noresume() and pm_runtime_put_noidle() will be used for incrementing and decrementing it, respectively.
