3.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Stephen Boyd <sboyd@xxxxxxxxxxxxxx>
commit bcd53f858d87f52843cc87764b283999126a50d6 upstream.
Timur reports that this code crashes if nfunctions is 0. Fix the
loop iteration to only consider valid elements of the functions
array.
