- pm_runtime_disable call is missed in some of the error cases
fix the same.
- In the error path pm_runtime_put_sync is called after pm_runtime_disable
fix the same.
- keypad_data->keymap free was missed in one of the error path fix it.
Also while at it call pm_runtime_put_sync after the register access in probe
instead of waiting for input registration etc.
