Each suspend test is executed per output. Limit number of outputs tested to 3 by default. Add command-line option enabling execution on every output. v3->v4 - declare `data' as static (Mohammed) - add parenthesis around check (Mohammed) v2->v3 - add patch Signed-off-by: Michał Grzelak <redacted> --- tests/kms_hdr.c | 30 ++++++++++++++++++++++++++++-- 1 file changed, 28 insertions(+), 2 deletions(-)
