3.16.61-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Lee Jones lee.jones@linaro.org
commit 1768391c3674b0c6bdc4947121f15fb0c2f47ec4 upstream.
The COMP1 and COMP2 elements are in 0 and 1 respectively so this code is accessing the wrong elements and one space beyond the end of the array.
The "id" variable is never COMP (0) so that code can be removed.
