ASoC: davinci-mcasp: Correct pm status check in suspend callback
pm_runtime_enabled() will only tell if the pm runtime has been enabled for the device, which is done at probe time but will not tell the actual power state of the device. pm_runtime_active() provides this information. This patch fixes a kernel crash when doing suspend when McASP is not active. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Mark Brown <broonie@kernel.org>
