X-Git-Tag: v3.9-rc1~126^2~32 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=192fef18d0f5ac9a05a93ff6314fc9865c10fbf9;p=pandora-kernel.git usb: enable usb port device's async suspend. This patch is to set power.async_suspend for usb port in order to allow it to be suspended and resumed asynchronously during system sleep transitions. The power.async_suspend flag is also set for devices that don't have suspend or resume callbacks, because otherwise they would make the main suspend/resume thread wait for their "asynchronous" children (during suspend) or parents (during resume), effectively negating the possible gains from executing these devices' suspend and resume callbacks asynchronously.
