Subject: KVM: s390: Function documentation fixes
Git-commit: 25b5476a294cd5f7c7730f334f6b400d30bb783d
Patch-mainline: v5.15-rc7
References: jsc#PED-579
The latest compile changes pointed us to a few instances where we use
the kernel documentation style but don't explain all variables or
don't adhere to it 100%.
It's easy to fix so let's do that.
