USB: serial: introduce a flag into the usb serial layer to tell drivers that their URBs are killed due to suspension
This patch introduces a flag into the usb serial layer to tell drivers that their URBs are killed due to suspension. That is necessary to let drivers know whether they should report an error back. Signed-off-by: Oliver Neukum <oneukum@suse.de> Hi Greg, this is for 2.6.30. Patches to use this in drivers are under development. Regards Oliver
