No, this patch is not acceptable.

This has been beaten to death in previous threads.
The problem is a mismatch in your kernel config between
generic hdlc (M) and synclink (Y).

synclink drivers can *optionally* support generic hdlc.
You *must* be able to build synclink driver without generic hdlc.
Because of this you *can't* just put in the generic hdlc dependency.

Several alternative patches were posted (3 or 4 months) ago.
No particular patch won the approval of all kernel developers,
so nothing was done.
