Subject: [PATCH] lib: sbi: pmu: Improve loop in pmu_ctr_find_hw
Date: Mon, 21 Jul 2025 18:07:12 +0200	[thread overview]
Message-ID: <20250721160712.8766-1-maherme.dev@gmail.com> (raw)

We do not need to iterate over all values in the loop,
we can break the loop when we found a valid counter
that is not started yet.
