Subject: [PATCH] mei: hw: don't use one element arrays
Git-commit: 92ca3dd4867bafbfd026b06d53737d61ded1bd27
Patch-mainline: v5.9-rc1
References: jsc#SLE-13387

Replace the single element arrays with a simple value type u8 reserved,
even thought is is not used for dynamically sized trailing elements
it confuses the effort of replacing one-element arrays with
flexible arrays for that purpose.
