SYNOPSIS

void drm_atomic_clean_old_fb(struct drm_device * dev, unsigned plane_mask, int ret);

ARGUMENTS

dev

drm device to check.

plane_mask

plane mask for planes that were updated.

ret

return value, can be -EDEADLK for a retry.

DESCRIPTION

Before doing an update plane->old_fb is set to plane->fb, but before dropping the locks old_fb needs to be set to NULL and plane->fb updated. This is a common operation for each atomic update, so this call is split off as a helper.
