[PATCH v2 19/25] powerpc/signal32: Remove ifdefery in middle of if/else
From: Christophe Leroy
Date: Tue Aug 18 2020 - 13:20:35 EST
MSR_TM_ACTIVE() is always defined and returns always 0 when
CONFIG_PPC_TRANSACTIONAL_MEM is not selected, so the awful
ifdefery in the middle of an if/else can be removed.
