The patch titled
generic HDLC synclink config mismatch fix
has been removed from the -mm tree. Its filename was
generic-hdlc-synclink-config-mismatch-fix.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: generic HDLC synclink config mismatch fix
From: Paul Fulghum <paulkf@xxxxxxxxxxxxx>
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.
