H A D | ec_sys.c | diff b66f86849414807745b5c2129e2de5f27a788c9f Thu Nov 25 11:36:16 CET 2021 Hans de Goede <hdegoede@redhat.com> ACPI: EC: Mark the ec_sys write_support param as module_param_hw()
Using write_support=1 with the ec_sys module changes the mode of the "io" debugfs file to 0600. This will cause any attempts to access it under a kernel in lockdown mode to return -EPERM, which makes the entire ec_sys module unusable.
Use the special module_param_hw() macro for module parameters which may not be used while in lockdown mode, to avoid this.
