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;
