From 7525cea3ef9384054a30f25ebb501234befecdcb Mon Sep 17 00:00:00 2001 From: Srinivas Pandruvada Date: Tue, 3 Oct 2023 09:32:33 -0700 Subject: platform/x86: intel_speed_select_if: Remove hardcoded map size MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The driver is using 256 as the size while calling devm_ioremap(). The maximum offset can be obtained from isst_mmio_range. Add a field "size" to the isst_mmio_range and use it instead of hardcoding. No functional impact is expected.
