Subject: [PATCH] ASoC: SOF: ipc3-loader: Print out the non matching ext_man magic number
Git-commit: b9cb044f35fd5d6fdff92a0be23b020372525fef
Patch-mainline: v6.0-rc1
References: jsc#PED-850

Print out the found extended manifest magic number in case it is not
matching with the expected one (0x6e614d58) in debug level.
It is fairly unlikely that the firmware does not have ext_man section and
the found value in place of the magic number can help rootcausing boot
related issues.
