PM: sleep: core: mark 2 functions as __init to save some memory

2020-06-23T15:35:33Z

'early_resume_init()' and 'late_resume_init() 'are only called respectively via 'early_resume_init' and 'late_resume_init'. They can be marked as __init to save a few bytes of memory. Signed-off-by: Christophe JAILLET [ rjw: Subject edits ] Signed-off-by: Rafael J. Wysocki

kernel: rename show_stack_loglvl() => show_stack()

2020-06-09T16:39:13Z

Now the last users of show_stack() got converted to use an explicit log level, show_stack_loglvl() can drop it's redundant suffix and become once again well known show_stack().

power: use show_stack_loglvl()

PM: runtime: Replace pm_runtime_callbacks_present()

2020-05-29T16:03:12Z

The name of pm_runtime_callbacks_present() is confusing, because it suggests that the device has PM-runtime callbacks if 'true' is returned by that function, but in fact that may not be the case, so replace it with pm_runtime_has_no_callbacks() which is not ambiguous. No functional impact. Signed-off-by: Rafael J. Wysocki Reviewed-by: Ulf Hansson

PM: runtime: Make clear what we do when conditions are wrong in rpm_suspend()

2020-05-25T08:54:39Z

rpm_suspend() simple bails out when conditions are wrong. But this is not immediately obvious from the code. Make it clear what we do when conditions are wrong in rpm_suspend(). Signed-off-by: Andy Shevchenko Signed-off-by: Rafael J. Wysocki

Rename DPM_FLAG_LEAVE_SUSPENDED to DPM_FLAG_MAY_SKIP_RESUME which matches its purpose more closely. No functional impact. Suggested-by: Alan Stern Signed-off-by: Rafael J. Wysocki Acked-by: Wolfram Sang # for I2C Acked-by: Alan Stern Acked-by: Bjorn Helgaas

PM: sleep: core: Rename dev_pm_smart_suspend_and_suspended()

2020-04-24T19:32:41Z

Because all callers of dev_pm_smart_suspend_and_suspended use it only for checking whether or not to skip driver suspend callbacks for a device, rename it to dev_pm_skip_suspend() in analogy with dev_pm_skip_resume(). No functional impact. Suggested-by: Alan Stern Signed-off-by: Rafael J. Wysocki Acked-by: Alan Stern Acked-by: Bjorn Helgaas
