Subject: [PATCH 2/3] memory: tegra264: drop redundant tegra264_mc_icc_aggregate()
Date: Wed, 27 May 2026 19:31:26 +0530	[thread overview]
Message-ID: <20260527140127.49172-3-sumitg@nvidia.com> (raw)
In-Reply-To: <20260527140127.49172-1-sumitg@nvidia.com>

tegra264_mc_icc_aggregate() does nothing on top of icc_std_aggregate
except an early return on !mc->bwmgr_mrq_supported.
tegra264_mc_icc_set() already returns early on the same condition,
before reading any of the aggregated avg_bw / peak_bw values.  This
makes the early return in aggregate() redundant.  So, set
tegra264_mc_icc_ops.aggregate to icc_std_aggregate and drop the
helper.
