Clang is more aggressive about -Wformat warnings when the format flag specifies a type smaller than the parameter. It turns out that gsi is an int. Fixes: drivers/acpi/evged.c:105:48: warning: format specifies type 'unsigned char' but the argument has type 'unsigned int' [-Wformat] trigger == ACPI_EDGE_SENSITIVE ? 'E' : 'L', gsi); ^~~ Link: https://github.com/ClangBuiltLinux/linux/issues/378 Fixes: ea6f3af4c5e6 ("ACPI: GED: add support for _Exx / _Lxx handler methods") Acked-by: Ard Biesheuvel <ardb@kernel.org> Signed-off-by: Nick Desaulniers <ndesaulniers@google.com> --- drivers/acpi/evged.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
