From bd7791078ac223f5e96810c36b5cddf767945d3d Mon Sep 17 00:00:00 2001 From: Isaku Yamahata Date: Fri, 13 Dec 2024 14:30:00 -0800 Subject: [PATCH] KVM: selftests: Add printf attribute to _no_printf() Annotate the KVM selftests' _no_printf() with the printf format attribute so that the compiler can help check parameters provided to pr_debug() and pr_info() irrespective of DEBUG and QUIET being defined.
