tools: PCI: Fix broken pcitest compilation
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); Fixes: fef31ecaaf2c ("tools: PCI: Fix compilation warnings") Signed-off-by: Alan Mikhak <alan.mikhak@sifive.com> Signed-off-by: Lorenzo Pieralisi <lorenzo.pieralisi@arm.com> Reviewed-by: Paul Walmsley <paul.walmsley@sifive.com>
