4 Subject: [PATCH] drm/atomic: Pass the full state to CRTC atomic_check
5 MIME-Version: 1.0

9 Commit 29b77ad7b9ca8c87152a1a9e8188970fb2a93df4 upstream.
10
11 The current atomic helpers have either their object state being passed as
12 an argument or the full atomic state.
13
14 The former is the pattern that was done at first, before switching to the
15 latter for new hooks or when it was needed.
16
17 Let's start convert all the remaining helpers to provide a consistent
18 interface, starting with the CRTC's atomic_check.
19
20 The conversion was done using the coccinelle script below,
21 built tested on all the drivers and actually tested on vc4.
