Subject[PATCH 4.14 059/496] ARC: Fix malformed ARC_EMUL_UNALIGNED default
Date
4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ulf Magnusson <ulfalizer@gmail.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.
