From 921e672dee91af86f8f9e44a067c735ebac0744b Mon Sep 17 00:00:00 2001 From: Pierre Gondois Date: Tue, 24 Jan 2023 16:40:48 +0100 Subject: [PATCH] cacheinfo: Remove unused check in init_cache_level() commit e75d18cecbb3 ("arm64: cacheinfo: Fix incorrect assignment of signed error value to unsigned fw_level") checks the fw_level value in init_cache_level() in case the value is negative. Remove this check as the error code is not returned through fw_level anymore, and reset fw_level if acpi_get_cache_info() failed. This allows to try fetching the cache information from clidr_el1.
