From 2e0cf14e144593f8b364f8741f7196d829f3b427 Mon Sep 17 00:00:00 2001 From: Alexandru Gagniuc Date: Sun, 28 Dec 2014 20:38:32 -0600 Subject: northbridge/amd/pi/northbridge.c: Remove superfluous logic operand The "((1ull << (sizeof(modules) * 8)) - 1)" statement evaluates to 0xffffffff, but there's no need to AND with that value, as 'modules' is already 32-bit. The '&&' is most likely a typo, which meant bitwise and, as indicated by the structure of thus operation. Remove this superfluous statement. This also fixes a clang warning.
