Hi,
Thanks for the patch!

I would re-write
1. The commit subject to:
   Fix wrong warning on configure_accelerator
2. The commit message to:
   No need to continue to iterate over the accelerators list
   after a match is found, even if it is not supported.

Seems like the right thing to do.

Thanks,
