By using ftw, we avoid the issue of having to handle directory recursion ourselves and can focus on the test of checking the reading a sysfs/debugfs does not break runtime suspend. In the process, disregard errors when opening the individual files as they may fail for other reasons. v2: Bracket the file open/close with the wait_for_suspended() tests. Whilst the fd is open, it may be keeping the device awake, e.g. i915_forcewake_user. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Tested-by: Jari Tahvanainen <jari.tahvanainen@intel.com>
