The patch titled
mISDN: endian annotations for struct zt
has been removed from the -mm tree. Its filename was
misdn-endian-annotations-for-struct-zt.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: mISDN: endian annotations for struct zt
From: Harvey Harrison <harvey.harrison@xxxxxxxxx>
Found two possible bugs where the z1 value was used directly without
byteswapping.
