Subject: [PATCH 4.9 103/329] ARC: Fix malformed ARC_EMUL_UNALIGNED default
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ulf Magnusson <ulfalizer@...il.com>
[ Upstream commit 827cc2fa024dd6517d62de7a44c7b42f32af371b ]
'default N' should be 'default n', though they happen to have the same
effect here, due to undefined symbols (N in this case) evaluating to n
in a tristate sense.
Remove the default from ARC_EMUL_UNALIGNED instead of changing it. bool
and tristate symbols implicitly default to n.
