Subject: [PATCH 1/2] tools: PCI: Fix broken pcitest compilation
Date: Thu, 23 May 2019 13:14:23 -0700 [thread overview]
Message-ID: <1558642464-9946-2-git-send-email-alan.mikhak@sifive.com> (raw)
In-Reply-To: <1558642464-9946-1-git-send-email-alan.mikhak@sifive.com>
From: Alan Mikhak <alan.mikhak@sifive.com>
Fixes: fef31ecaaf2c ("tools: PCI: Fix compilation warnings")
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);
