From 814bde99ee809c172a409829889d1bafc3e4bcf7 Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Tue, 3 Jul 2018 09:50:17 +0200 Subject: drm/connector: Make ->atomic_commit() optional Not all writeback connector implementations might want to commit things from the connector driver. Some, like the malidp driver, commit things from their main commit_tail() function, and would rather not have to implement a dummy hook for drm_connector_helper_funcs.atomic_commit(). Make this function optional and reflect this fact in the doc.
