Subject[PATCH 5.4 221/475] selftests/bpf/test_lirc_mode2.sh: Exit with proper code
Date
From: Hangbin Liu <liuhangbin@gmail.com>

[ Upstream commit ec80906b0fbd7be11e3e960813b977b1ffe5f8fe ]

When test_lirc_mode2_user exec failed, the test report failed but still
exit with 0. Fix it by exiting with an error code.

Another issue is for the LIRCDEV checking. With bash -n, we need to quote
the variable, or it will always be true. So if test_lirc_mode2_user was
not run, just exit with skip code.

Fixes: 6bdd533cee9a ("bpf: add selftest for lirc_mode2 type program")
