[igt-dev] [PATCH v2 i-g-t 17/23] tests/kms_dither: Dont assert if debugfs is not present

[venkata.sai.patnana at intel.com]

From: Bhanuprakash Modem <bhanuprakash.modem at intel.com>

As Dither_CC1 debugfs changes are not preset on older platforms, we need
not to abort the test. So if the debugfs is not present, just consider
the value as zero.
