[alsa-devel] [PATCH 2/2] ASoC: rockchip: i2s: add support for grabbing output clock to codec

differences from v2 (after the cut).  Please have Kever or Chris
review your next patch before sending it out since I think they are
familiar with the process.

You still forgot the blank line here requested by Heiko.  Please try
