 Description:   Reading this file gives the current selected profile for this
                device. Writing this file with one of the strings from
                platform_profile_choices changes the profile to the new value.
+
+               This file can be monitored for changes by polling for POLLPRI,
+               POLLPRI will be signalled on any changes, independent of those
+               changes coming from a userspace write; or coming from another
+               source such as e.g. a hotkey triggered profile change handled
+               either directly by the embedded-controller or fully handled
+               inside the kernel.
