hook_entity_view_alter() misses an $entity parameter

Related hooks are:

core/modules/comment/comment.api.php:function hook_comment_view_alter(&$build) {
core/modules/entity/entity.api.php:function hook_entity_view_alter(&$build, $type) {
core/modules/node/node.api.php:function hook_node_view_alter(&$build) {
core/modules/taxonomy/taxonomy.api.php:function hook_taxonomy_term_view_alter(&$build) {
core/modules/user/user.api.php:function hook_user_view_alter(&$build) {

Thanks! The patch looks good to me, -> RTBC.

@hook_entity_view()
oh, I see. This overlaps with #1618136: Remove $type from entity hooks a bit now, but that one needs to be rerolled anyway.

Removing sprint tag.
