[igt-dev] [PATCH i-g-t v3 3/3] tests/kms_writeback: Use a garbage X value to create fill our test buffer

[Maxime Ripard]

Since we use buffers in XRGB8888, whatever value we have in X should be
ignored by the drivers and the hardware. However, since we always use
0xff in our test, whether that is the case or not cannot be determined.

Let's use a garbage value (but consistent across test runs) to make sure
it doesn't have any impact on the writeback output.
