PM: runtime: Wrapper macros for ACQUIRE()/ACQUIRE_ERR()
Add wrapper macros for ACQUIRE()/ACQUIRE_ERR() and runtime PM usage counter guards introduced recently: pm_runtime_active_try, pm_runtime_active_auto_try, pm_runtime_active_try_enabled, and pm_runtime_active_auto_try_enabled. The new macros should be more straightforward to use. For example, they can be used for rewriting a piece of code like below: ACQUIRE(pm_runtime_active_try, pm)(dev); if ((ret = ACQUIRE_ERR(pm_runtime_active_try, &pm))) return ret; in the following way: PM_RUNTIME_ACQUIRE(dev, pm); if ((ret = PM_RUNTIME_ACQUIRE_ERR(&pm))) return ret; If the original code does not care about the specific error code returned when attepmting to resume the device: ACQUIRE(pm_runtime_active_try, pm)(dev); if (ACQUIRE_ERR(pm_runtime_active_try, &pm)) return -ENXIO; it may be changed like this: PM_RUNTIME_ACQUIRE(dev, pm); if (PM_RUNTIME_ACQUIRE_ERR(&pm)) return -ENXIO; Link: https://lore.kernel.org/linux-pm/5068916.31r3eYUQgx@rafael.j.wysocki/ Signed-off-by: Rafael J.
