Subject: [PATCH AUTOSEL 5.4 13/57] ASoC: topology: Fix endianness issue

From: Amadeusz Sławiński <amadeuszx.slawinski@...ux.intel.com>

[ Upstream commit 26d87881590fd55ccdd8f829498d7b3033f81990 ]

As done in already existing cases, we should use le32_to_cpu macro while
accessing hdr->magic. Found with sparse.
