Hello everyone,

Fixed M_CAN_DBTP corrupt register contents:
* NBTP_xxx defines were being used instead of DBTP_xxx.
* reg_btp was not getting ORed with the possibly-existing DBTP_TDC flag.

Hello Marc,

I hope it's in the correct format now.

Fixed M_CAN_DBTP corrupt register contents:
* NBTP_xxx defines were being used instead of DBTP_xxx.
* reg_btp was not getting ORed with the possibly-existing DBTP_TDC flag.

Thanks for the patch, looks better. However your mailer converts tabs to
spaces. For further contributions try to use "git send-email". I've
applied the patch to linux-can/testing.

Marc
