[ Upstream commit 8a5e0af240e07dd3d4897eb8ff52aab757da7fab ]
pcitest is currently broken due to the following compiler error and related warning. Fix by changing the run_test() function signature to return an integer result.
pcitest.c: In function run_test: pcitest.c:143:9: warning: return with a value, in function returning void return (ret < 0) ? ret : 1 - ret; /* return 0 if test succeeded */
pcitest.c: In function main: pcitest.c:232:9: error: void value not ignored as it ought to be return run_test(test);
