From b2534c28b23b099fc399021283ffaf9f40513abf Mon Sep 17 00:00:00 2001 From: Thomas Richter Date: Fri, 23 Jun 2023 11:22:40 +0200 Subject: s390/cpum_sf: handle casts consistently The casts are written in two different notations: (cast) expression and (cast)expression Convert statements with the first notation to the second notation. No functional change.
