[PATCH 0/2] iommu/arm-smmu: Use FIELD_MODIFY() for bitfield operations

From: Hans Zhang

Date: Thu Apr 30 2026 - 12:53:05 EST


Replace open-coded bitfield modifications with the standard FIELD_MODIFY()
macro. This improves code readability and adds type/range checking without
functional changes.

FIELD_MODIFY() internally performs the same mask-clear + set operation but
eliminates repetitive boilerplate.

Hi, If the Maintainers think it's not necessary, please ignore it.
