Subject: [media] ene_ir: disable the device if wake is disabled
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b5daad2f13c90ef3175d201450543fd0a1627bdd;p=openwrt%2Fstaging%2Fblogic.git

[media] ene_ir: disable the device if wake is disabled

It doesn't hurt and on my notebook despite clearing the
wake flag the remote still wakes up the system.

This way it doesn't.
