Subject: [PATCH] input: extend EV_LED
Date: Sun, 11 Feb 2007 11:02:19 +0100 [thread overview]
Message-ID: <45CEE9AB.2020208@freemail.hu> (raw)
Extend EV_LED handling code so that it can handle not
only two states (on/off) but also others. For example
a LED can blink using hardware acceleration. The code
changed so that it is similar to the code at EV_SND.
