Subject: [PATCH 0/2] iommu/arm-smmu: Use FIELD_MODIFY() for bitfield operations
Date: Fri, 1 May 2026 00:45:43 +0800 [thread overview]
Message-ID: <20260430164545.49637-1-18255117159@163.com> (raw)
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.
