[PATCH 1/5] drm/atomic: Fix atomic helpers to use the new iterator macros, v3.
Maarten Lankhorst
maarten.lankhorst at linux.intel.com
Thu Mar 2 13:29:49 UTC 2017
There are new iterator macros that annotate whether the new or old
state should be used. This is better than using a state that depends on
whether it's called before or after swap. For clarity, also rename the
variables from $obj_state to (old,new)_$obj_state as well.
Changes since v1:
- Use old/new_*_state for variable names as much as possible. (pinchartl)
- Expand commit message.
Changes since v2:
- Rebase on top of link training patches.
- free -> cleanup (pinchartl)
