[alsa-devel] [PATCH 1/1] ASoC: Fix compilation error with davinci-sffsdr module

[Hugo Villeneuve]

The SFFSDR audio codec sampling frequency clock is generated by
a FPGA, and set by the FPGA driver. The FPGA driver is not yet
in the mainline kernel, so that is why an extern declaration is
used in the meantime.
