[igt-dev] [PATCH i-g-t 7/8] tests/kms_chamelium: don't abort audio test on first fail

[Simon Ser]

The audio test is repeated with a few different frequencies. When the test
fails for one frequency, continue testing other frequencies so that we get a
better understanding of the situation: is only one frequency failing, or are
all of them failing?
