-Compatibility notes:
-
-ibm-acpi and thinkpad-acpi 0.15 (mainline kernels before 2.6.23) never
-supported the input layer, and sent events over the procfs ACPI event
-interface.
-
-To avoid sending duplicate events over the input layer and the ACPI
-event interface, thinkpad-acpi 0.16 implements a module parameter
-(hotkey_report_mode), and also a sysfs device attribute with the same
-name.
-
-Make no mistake here: userspace is expected to switch to using the input
-layer interface of thinkpad-acpi, together with the ACPI netlink event
-interface in kernels 2.6.23 and later, or with the ACPI procfs event
-interface in kernels 2.6.22 and earlier.
-
-If no hotkey_report_mode module parameter is specified (or it is set to
-zero), the driver defaults to mode 1 (see below), and on kernels 2.6.22
-and earlier, also allows one to change the hotkey_report_mode through
-sysfs. In kernels 2.6.23 and later, where the netlink ACPI event
-interface is available, hotkey_report_mode cannot be changed through
-sysfs (it is read-only).
-
-If the hotkey_report_mode module parameter is set to 1 or 2, it cannot
-be changed later through sysfs (any writes will return -EPERM to signal
-that hotkey_report_mode was locked. On 2.6.23 and later, where
-hotkey_report_mode cannot be changed at all, writes will return -EACCES).
-
-hotkey_report_mode set to 1 makes the driver export through the procfs
-ACPI event interface all hot key presses (which are *also* sent to the
-input layer). This is a legacy compatibility behaviour, and it is also
-the default mode of operation for the driver.
-
-hotkey_report_mode set to 2 makes the driver filter out the hot key
-presses from the procfs ACPI event interface, so these events will only
-be sent through the input layer. Userspace that has been updated to use
-the thinkpad-acpi input layer interface should set hotkey_report_mode to
-2.
-
-Hot key press events are never sent to the ACPI netlink event interface.
-Really up-to-date userspace under kernel 2.6.23 and later is to use the
-netlink interface and the input layer interface, and don't bother at all
-with hotkey_report_mode.
