From 9085b23b668ad5aca62df4f071b306a47152e6b3 Mon Sep 17 00:00:00 2001 From: Bjorn Andersson Date: Tue, 5 Dec 2023 14:14:00 -0800 Subject: interconnect: qcom: icc-rpm: Fix peak rate calculation Per the commit message of commit 'dd014803f260 ("interconnect: qcom: icc-rpm: Add AB/IB calculations coefficients")', the peak rate should be 100/ib_percent. But, in what looks like a typical typo, the numerator value is discarded in the calculation. Update the implementation to match the described intention.
