[PATCH 1/1] module: fix sprintf format specifier in param_get_byte()

From: Christoph Jaeger
Date: Tue Aug 06 2013 - 17:13:34 EST


In param_get_byte(), to which the macro STANDARD_PARAM_DEF(byte, ...) expands,
"%c" is used to print an unsigned char. So it gets printed as a character what
is not intended here. Use "%hhu" instead.
