From: Srinivasa Rao Mandadapu <srivasam@codeaurora.org>

commit 9922f50f7178496e709d3d064920b5031f0d9061 upstream.

The max boundary check while parsing dai ids makes
sound card registration fail after common up dai ids.

Fixes: cd3484f7f138 ("ASoC: qcom: Fix broken support to MI2S TERTIARY and QUATERNARY")
