Hi Oliver,

Thanks for your patch Carsten!
There should be at least one sentence in the commit message even when the
subject almost covers the story ;-)
@Carsten, thanks for the patch!
Acked-by: Jimmy Assarsson <extja@xxxxxxxxxx>
Tested-by: Jimmy Assarsson <extja@xxxxxxxxxx>
Can you also please change the subject to
can: kvaser_usb: add len8_dlc support for kvaser_usb_leaf
to follow up with the other len8_dlc patches?
@Jimmy: AFAIK Carsten only has a Kvaser USB Leaf for testing. Can you
probably provide and test a similar improvement for the Kvaser USB Hydra
hardware?
@Oliver, yes, I'll fix this for the remaining Kvaser USB devices.
I'll try to send a patch for it by the end of the week.
Best regards,
jimmy
Hi Carsten,
I've implemented cc-len8-dlc support for the Kvaser USB Hydra devices.
Is it OK if I add my changes to your patch, and send it is as a V2?
Best regards,
jimmy
Many thanks,
Oliver
