Subject: [media] winbond-cir: fix idle mode
X-Git-Tag: v3.9-rc5~2^2~695
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e5eda7faea23c28836f17487962c6539fd3b3e27;p=platform%2Fkernel%2Flinux-3.10.git

[media] winbond-cir: fix idle mode

The receiver is never disabled by idle mode since rxstate never gets set
to RXSTATE_ACTIVE, so we keep on getting interrupts after the first IR
activity ends. Note that ir_raw_event_reset() already calls
ir_raw_event_handle().
