Subject: [PATCH] ASoc: rockchip: i2s: Fix RPM imbalance
Git-commit: b1e620e7d32f5aad5353cc3cfc13ed99fea65d3a
Patch-mainline: v5.4-rc5
References: bsc#1051510

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.
