[igt-dev] [PATCH i-g-t 1/8] lib/psr: Increase the buffer lenght that stores the output of i915_edp_psr_status

[José Roberto de Souza]

Sometimes 512 bytes is not enoght to store the whole
i915_edp_psr_status potentially causing fail in tests that depends
in the content that is out of this 512 bytes.
