Most of the implementations of PUTC_LL() takes "char" (some take "int"), not "unsigned char". Moreover, puts_ll() takes an argument with "const char *" type. Let's drop "unsigned" from the prototype of putc_ll(). Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
