[PATCH v3] drm: Differentiate the lack of an interface from invalid parameter
Chris Wilson
chris at chris-wilson.co.uk
Wed Sep 12 09:29:42 UTC 2018
If the ioctl is not supported on a particular piece of HW/driver
combination, report ENOTSUPP so that it can be easily distinguished from
both the lack of the ioctl and from a regular invalid parameter.
v2: Across all the kms ioctls we had a mixture of reporting EINVAL,
ENODEV and a few ENOTSUPP (most where EINVAL) for a failed
drm_core_check_feature(). Update everybody to report ENOTSUPP.
