Re: [PATCH 1/2] dma: pl330: improve pl330_tx_status() function

[Padma Venkat]

Hi Robert,

I tested your patches on exynos5420 peach-pit with audio playback and
got some underrun error.
I posted a similar patch in the below link.

https://patchwork.kernel.org/patch/5384551/

Please do review the same.

Thanks
Padma
