[PATCH] generic HDLC synclink config mismatch fix
Fix compile errors on mismatch between generic HDLC and synclink drivers.
Notes:
generic HDLC support for synclink drivers is *optional* so you can't just
use depend on in Kconfig
This solution is deemed the best after 7 months of review and criticism by
many developers including AKPM. Read the threads on LKML before posting
about this solution.
