drm: Move property validation to a helper, v2.
Property lifetimes are equal to the device lifetime, so the separate drm_property_find is not needed. The pointer can be retrieved from the properties member, which saves us some locking and a extra lookup. The lifetime for properties is until the device is destroyed, which happens late in the device unload path. kms_atomic is also testing for invalid properties which returns -ENOENT, to be consistent return -ENOENT for valid properties that don't appear on the object property list. Changes since v1: - Return -ENOENT for invalid properties to make kms_atomic pass. - Change commit message slightly to take this into account. Testcase: kms_atomic Testcase: kms_properties Fixes: 4e9951d96093 ("drm/atomic: Reject properties not part of the object.")
