0030 This file can be monitored for changes by polling for POLLPRI,
0031 POLLPRI will be signalled on any changes, independent of those
0032 changes coming from a userspace write; or coming from another
0033 source such as e.g. a hotkey triggered profile change handled
0034 either directly by the embedded-controller or fully handled
0035 inside the kernel.
