From 12c44ab8b401c29d8d3569aaea34da662b8ece1d Mon Sep 17 00:00:00 2001 From: Ahmad Khalifa Date: Tue, 4 Oct 2022 22:01:01 +0100 Subject: hwmon: (it87) Add param to ignore ACPI resource conflicts Add parameter to ignore ACPI resource conflicts as an alternate to using 'acpi_enforce_resources=lax'. Some BIOSes reserve resources and don't use them and the system wide parameter may result in failures to certain drivers.
