From 5db0f6e880eb99ad400d5f1c646dffc7fd939c78 Mon Sep 17 00:00:00 2001 From: Stephane Viau Date: Fri, 20 Feb 2015 12:40:58 -0500 Subject: drm/msm/mdp5: fixup "drm/msm: fix fallout of atomic dpms changes" Commit 0b776d457b94 ("drm/msm: fix fallout of atomic dpms changes") has a typo in both mdp5_encoder_helper_funcs and mdp5_crtc_helper_funcs definitions: .dpms entry should be replaced by .disable and .enable Also fixed a typo in mdp5_encoder_enable(). Note that these typos are only present for MDP5. MDP4 is fine.

This can happen when we try to move a cursor but the CRTC's CTL (CONTROL) has not been allocated yet (inactive CRTC). It can also happens when we .atomic_check()/.atomic_flush() on a disabled CRTC. A CTL needs to be kept as long as the CRTC is alive. Releasing it after the last VBlank is safer than in .atomic_flush().
