[PATCH] KVM: SVM: Fix an off-by-one typo in the comment for enabling AVIC by default

From: Sean Christopherson
Date: Wed Jan 07 2026 - 17:01:25 EST


Fix a goof in the comment that documents KVM's logic for enabling AVIC by
default to reference Zen5+ as family 0x1A (Zen5), not family 0x19 (Zen4).
The code is correct (checks for _greater_ than 0x19), only the comment is
flawed.
