4 Subject: [PATCH] drm/atomic: Pass the full state to CRTC atomic begin
5 and flush

10 Commit f6ebe9f9c9233a6114eb922aba9a0c9ccc2d2e14 upstream.
11
12 The current atomic helpers have either their object state being passed as
13 an argument or the full atomic state.
14
15 The former is the pattern that was done at first, before switching to the
16 latter for new hooks or when it was needed.
17
18 Let's start convert all the remaining helpers to provide a consistent
19 interface, starting with the CRTC's atomic_begin and atomic_flush.
20
21 The conversion was done using the coccinelle script below, built tested on
22 all the drivers and actually tested on vc4.
