How should we proceed with this patch?

Applying the patch on e.g. 3.2.102 also leads to

patching file net/can/bcm.c
Hunk #1 FAILED at 67.
Hunk #2 FAILED at 140.
Hunk #3 succeeded at 847 with fuzz 2 (offset -26 lines).
Hunk #4 succeeded at 1018 with fuzz 2 (offset -39 lines).
2 out of 4 hunks FAILED -- saving rejects to file net/can/bcm.c.rej

The first two hunks just adding a define and and function *somewhere* at the top of the C file.

I can provide patches for the requested stable kernels once we have a reference for the upstream commit hash.

Would that be ok for you?

Best regards,
Oliver
