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 ?
