ALSA: hdac_regmap - fix the register access for runtime PM
Call path:
1) snd_hdac_power_up_pm()
2) snd_hdac_power_up()
3) pm_runtime_get_sync()
4) __pm_runtime_resume()
5) rpm_resume()
The rpm_resume() returns 1 when the device is already active.
Because the return value is unmodified, the hdac regmap read/write
functions should allow this value for the retry I/O operation, too.
