[PATCH 3.18 23/28] MIPS: microMIPS: Fix incorrect mask in insn_table_MM

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

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

From: Gustavo A. R. Silva <garsilva@xxxxxxxxxxxxxx>

commit 77238e76b9156d28d86c1e31c00ed2960df0e4de upstream.

It seems that this is a typo error and the proper bit masking is
"RT | RS" instead of "RS | RS".

This issue was detected with the help of Coccinelle.
