[PATCH 2.4.21-pre3-bk RESEND 2] sonypi driver update

From: Stelian Pop (stelian@popies.net)
Date: Thu Jan 09 2003 - 09:13:23 EST


Hi,

This little patch (present in 2.5) changes the way button release events
are reported by the sonypi driver to the application: previously,
separate release events were detected for each button. However, many
buttons (example: the jogdial, the capture button, the back button etc)
share the same release event.

The attached patch propagates a single 'ANYBUTTON_RELEASED' event
to the userspace, leaving all state machine intelligence to the
application.

Kunihiko IMAI should be credited for his ideas and tests.

Alan, Marcelo, please apply.

Thanks,

Stelian.
