[PATCH 4.13 28/36] MIPS: microMIPS: Fix incorrect mask in insn_table_MM

From: Greg Kroah-Hartman
Date: Mon Nov 06 2017 - 04:14:49 EST


4.13-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.
