Revert "ASoC: soc-component: using pm_runtime_resume_and_get instead of pm_runtime_get_sync"
This reverts commit 08fc2a7448afc1660ec2f1b5c437fcd14155a7ee.
The reverted commit causes the following warnigs:
Runtime PM usage count underflow!
This is due to the fact that the pm_runtime_resume_and_get() is calling
pm_runtime_put_noidle() in case of < 0 return value of
pm_runtime_get_sync() which includes the -EACCES.
The change is wrong as -EACCES is returned in case of 'nested' get_sync()
and it is a valid use of PM runtime.
Fixes: 08fc2a7448af ("ASoC: soc-component: using pm_runtime_resume_and_get instead of pm_runtime_get_sync")
