[igt-dev] [PATCH] lib/igt_debugfs: skip test instead of assert if crc/control is invalid

[Mark Yacoub]

From: Mark Yacoub <markyacoub at google.com>

[Why]
Some drivers such as msm do not currently support debugfs yet.

[How]
Change igt_assert of opening "crtc-%d/crc/control" to igt_require_f.
Opening this file doesn't involved a complicated logic so assert isn't
required to verify that things are smooth. -1 indicates that the file
isn't supported by the driver.

Test: kms_atomic:plane-immutable-zpos on ChromeOS Trogdor(msm)
