Public bug reported:

 [Impact]
    Adding this patch addresses a specific audio issue with the tegra kernel.

 [Fix]
    ASoC: simple-card-utils: Increase maximum DAI links limit to 512

    The current limit of 128 is not sufficient when more components are
    added to the audio map on Tegra210 and later platforms. Thus it is
    resulting in probe failure.

    The requirement is of nearly ~200 DAI links. To give sufficient room
    for future additions the maximum limit is increased to 512 DAI links.
    This is a preparatory patch to add more components like resampler,
    mixer, multiplexers, demultiplexers and volume controllers to Tegra210
    and later platforms.

 This is upstream commit 7a226f2eabdc2e839d8f07c5ce087136f9c0f35c
