Subject: [PATCH] ASoC: SOF: IPC: fix implicit type overflow
Git-commit: 7c1d0e554a359cca77bfabd2a29b06f5322d172d
Patch-mainline: v5.11-rc1
References: jsc#SLE-16518

Implicit values may have a length of 15bits (s16) so we need to declare
the proper size so we don't get undefined behaviour. This appears to be
arch and compiler dependent. This commit is to keep the headers aligned
between the firmware and kernel. UBSan discovered this bug in the
firmware.
