From 624251b4b5a0c3261ce0d3f9031e26c553e9e13a Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Sat, 31 Oct 2020 10:15:24 -0500 Subject: [PATCH] net: ipa: avoid a bogus warning The previous commit added support for IPA having up to six source and destination resources. But currently nothing uses more than four. (Five of each are used in a newer version of the hardware.) I find that in one of my build environments the compiler complains about newly-added code in two spots. Inspection shows that the warnings have no merit, but this compiler does not recognize that. ipa_main.c:457:39: warning: array index 5 is past the end of the array (which contains 4 elements) [-Warray-bounds] (and the same warning at line 483) We can make this warning go away by changing the number of elements in the source and destination resource limit arrays--now rather than waiting until we need it to support the newer hardware. This change was coming soon anyway; make it now to get rid of the warning.
