[PATCH v6 14/28] arm64/sysreg: Standardise naming for ID_AA64PFR0_EL1.AdvSIMD constants
Mark Brown

Mon Sep 5 15:54:11 PDT 2022
The architecture refers to the register field identifying advanced SIMD as
AdvSIMD but the kernel refers to it as ASIMD. Use the architecture's
naming. No functional changes.
