Subject: [PATCH] ASoC: amd: Rectifying Unbalanced pm_runtime_enable! issue
Date: Tue, 30 Jun 2020 14:52:38 +0530	[thread overview]
Message-ID: <20200630092242.7799-1-Vishnuvardhanrao.Ravulapati@amd.com> (raw)

When snd_pci_acp3x driver loads we see:

WARNING kernel:snd_pci_acp3x 0000:04:00.5: Unbalanced pm_runtime_enable!
at boot time.
same can be observed in /var/log/messages/.

Modifying pm runtime sequence for fixing unbalanced pm issue.
