Subject: tools/testing/selftests/ipc/msgque.c: handle msgget failure return correctly
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=53942232369ec317f77dc8c2d5a0637bb85a6e84;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

tools/testing/selftests/ipc/msgque.c: handle msgget failure return correctly

A failed msgget causes the test to return an uninitialised value in ret.
Assign ret to -errno on error exit.
