When compiling with -Wformat, clang emits the following warning:
drivers/gpio/gpiolib-acpi.c:393:4: warning: format specifies type
'unsigned char' but the argument has type 'int' [-Wformat]
pin);
^~~
The types of these arguments are unconditionally defined, so this patch
updates the format character to the correct ones for ints and unsigned
ints.
