This patch (as1403b) is a backport of commit

48826626263d4a61d06fd8c5805da31f925aefa0 (USB: obey the sysfs
|
|
power/wakeup setting) to 2.6.{32,33}.stable. It turns out that the
|
|
bug it fixes does affect quite a few people using USB infrared
|
|
remotes. The symptom is that the remote can no longer wake up the
|
|
system from suspend.
|
|
|
|
This fixes Bugzilla #16043.

Red Hat Bugzilla #617559
