From 7158f609c94d006cbb2af24558401628cd1baebd Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Wed, 13 Aug 2014 15:25:55 -0500 Subject: tegra132: provide more robust array bounds checking Make sure the array size matches the number of supported FUNITs. Also remove the FUNIT_NONE enumeration so that there isn't an empty slot in the array at index 0. BUG=chrome-os-partner:31251 BRANCH=None TEST=Built when array wasn't large enough. Compiler threw an error.
