Subject: [PATCH 1/1] module: fix sprintf format specifier in param_get_byte()
Date: Tue, 6 Aug 2013 23:12:12 +0200 [thread overview]
Message-ID: <1375823532-24153-1-git-send-email-christophjaeger@linux.com> (raw)
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.
