[035/103] V4L/DVB: IR: fix keys beeing stuck down forever

2.6.35-stable review patch. If anyone has any objections, please let us know.

------------------

From: Maxim Levitsky <maximlevitsky@xxxxxxxxx>

commit e0172fd373ab77a83ea952fd6a75c612e1b0bf9e upstream.

The logic in ir_timer_keyup was inverted.

In case that values aren't equal,
the meaning of the time_is_after_eq_jiffies(ir->keyup_jiffies) is that
ir->keyup_jiffies is after the the jiffies or equally that
that jiffies are before the the ir->keyup_jiffies which is
exactly the situation we want to avoid (that the timeout is in the future)
Confusing Eh?
