The arguments related to IOMMU port name have been unused since commit 944fc36c31ed ("drm/msm: use upstream iommu") and can be removed. Signed-off-by: Drew Davenport <ddavenport@xxxxxxxxxxxx> --- Rob, in the original commit the port name stuff was left intentionally. Would it be alright to remove it now? drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c | 10 ++-------- drivers/gpu/drm/msm/disp/mdp4/mdp4_kms.c | 10 ++-------- drivers/gpu/drm/msm/disp/mdp5/mdp5_kms.c | 10 ++-------- drivers/gpu/drm/msm/msm_gpu.c | 5 ++--- drivers/gpu/drm/msm/msm_gpummu.c | 6 ++---- drivers/gpu/drm/msm/msm_iommu.c | 6 ++---- drivers/gpu/drm/msm/msm_mmu.h | 4 ++-- 7 files changed, 14 insertions(+), 37 deletions(-) diff --git a/drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c b/drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c index 58b0485dc375..3165c2db2541 100644 --- a/drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c +++ b/drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c @@ -30,10 +30,6 @@ #define CREATE_TRACE_POINTS #include "dpu_trace.h" -static const char * const iommu_ports[] = { - "mdp_0", -};
