From 79ac6834c255d9e3832209f3738d6bff7b87c743 Mon Sep 17 00:00:00 2001 From: Christoph Jaeger Date: Tue, 20 Aug 2013 15:33:18 +0930 Subject: module: fix sprintf format specifier in param_get_byte() 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.
