[PATCH v4 07/14] drm/tidss: oldi: Fix wrong return value from tidss_oldi_mode_valid()

[Tomi Valkeinen]

tidss_oldi_mode_valid() returns 'enum drm_mode_status', but the current
code returns -EINVAL or 0.

Fix it to return proper enum values.

Fixes: 86db652fc22f ("drm/tidss: Move OLDI mode validation to OLDI bridge mode_valid hook")
