drm: Rename plane->state variables in atomic update and disable
Some drivers are storing the plane->state pointer in atomic_update and atomic_disable in a variable simply called state, while the state passed as an argument is called old_state. In order to ease subsequent reworks and to avoid confusing or inconsistent names, let's rename those variables to new_state. This was done using the following coccinelle script, plus some manual changes for mtk and tegra. @ plane_atomic_func @ identifier helpers; identifier func; @@ ( static const struct drm_plane_helper_funcs helpers = { ..., .atomic_disable = func, ..., }; | static const struct drm_plane_helper_funcs helpers = { ..., .atomic_update = func, ..., }; ) @ moves_new_state_old_state @ identifier plane_atomic_func.func; identifier plane; symbol old_state; symbol state; @@ func(struct drm_plane *plane, struct drm_plane_state *old_state) { ... - struct drm_plane_state *state = plane->state; + struct drm_plane_state *new_state = plane->state; ... } @ depends on moves_new_state_old_state @ identifier plane_atomic_func.func; identifier plane; identifier old_state; symbol state; @@ func(struct drm_plane *plane, struct drm_plane_state *old_state) { <... - state + new_state ...> } @ moves_new_state_oldstate @ identifier plane_atomic_func.func; identifier plane; symbol oldstate; symbol state; @@ func(struct drm_plane *plane, struct drm_plane_state *oldstate) { ... - struct drm_plane_state *state = plane->state; + struct drm_plane_state *newstate = plane->state; ... } @ depends on moves_new_state_oldstate @ identifier plane_atomic_func.func; identifier plane; identifier old_state; symbol state; @@ func(struct drm_plane *plane, struct drm_plane_state *old_state) { <... - state + newstate ...> } @ moves_new_state_old_pstate @ identifier plane_atomic_func.func; identifier plane; symbol old_pstate; symbol state; @@ func(struct drm_plane *plane, struct drm_plane_state *old_pstate) { ... - struct drm_plane_state *state = plane->state; + struct drm_plane_state *new_pstate = plane->state; ... } @ depends on moves_new_state_old_pstate @ identifier plane_atomic_func.func; identifier plane; identifier old_pstate; symbol state; @@ func(struct drm_plane *plane, struct drm_plane_state *old_pstate) { <... - state + new_pstate ...> } Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Maxime Ripard <maxime@cerno.tech> Acked-by: Thomas Zimmermann <tzimmermann@suse.de> Link: https://patchwork.freedesktop.org/patch/msgid/20210219120032.260676-8-maxime@cerno.tech
