Subject: [PATCH] KVM: arm64: nv: Use reg_to_encoding() to get sysreg ID
Date: Sat, 11 Feb 2023 19:07:42 +0000	[thread overview]
Message-ID: <20230211190742.49843-1-oliver.upton@linux.dev> (raw)

Avoid open-coding and just use the helper to encode the ID from the
sysreg table entry.

No functional change intended.
