[PATCH 4.9 16/16] ACPI: GED: fix -Wformat

From: Greg Kroah-Hartman
Date: Fri Nov 20 2020 - 06:04:26 EST


From: Nick Desaulniers <ndesaulniers@xxxxxxxxxx>

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);
^~~
