[PATCH v4 3/3] ASoC: Intel: Skylake: Use NHLT API to search for blob
Cezary Rojewski

Fri Nov 26 14:47:39 CET 2021
From: Amadeusz Sławiński <amadeuszx.slawinski at linux.intel.com>
With NHLT enriched with new search functions, remove local code in
favour of them. This also fixes broken behaviour: search should be based
on significant bits count rather than container size.
