[PATCH 4.19 11/79] ASoc: rockchip: i2s: Fix RPM imbalance

From: Greg Kroah-Hartman
Date: Fri Nov 08 2019 - 14:18:04 EST


From: Robin Murphy <robin.murphy@xxxxxxx>

[ Upstream commit b1e620e7d32f5aad5353cc3cfc13ed99fea65d3a ]

If rockchip_pcm_platform_register() fails, e.g. upon deferring to wait
for an absent DMA channel, we return without disabling RPM, which makes
subsequent re-probe attempts scream with errors about the unbalanced
enable. Don't do that.
