[PATCH] ASoc: rockchip: i2s: Fix RPM imbalance

[PATCH] ASoc: rockchip: i2s: Fix RPM imbalance

[Robin Murphy]

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.
