commit 9debfb81e7654fe7388a49f45bc4d789b94c1103 upstream.
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); ^~~
