Hi Karthik,

Overall, the patch looks good to me, but I have dropped few minor 
comments to address.

Please drop this message, as we already moved dynamic subtests to 
another patch.

I think, we need a cleanup function to clear the states before exiting 
the subtest.

Note: As we are sanitizing the state before starting the subtest, no 
need of igt_display_reset in cleanup, but we just need to clear whatever 
the resources we used in subtest.

Instead of skipping dynamic subtest, we need to move this check to 
igt_fixture before calling the subtest. Also, need 
igt_require_pipe_crc() for crc test.

As we are sanitizing the state before starting the subtest, no need of 
igt_display_reset in exit, but we just need to make sure to clear 
whatever the resources we used in subtest.
