From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com
Current rsnd driver is using "%s[%d]" for mod name and ID, but, this ID portion might confusable. For example currently, CTU ID is 0 to 7, but using 00 to 13 (= 00, 01, 02, 03, 10, 11, 12, 13) is very best matching to datasheet.
In the future, we will support BUSIFn, but it will be more complicated numbering. To avoid future confusable code, this patch modify rsnd_mod_name() to return understandable name.
To avoid using pointless memory, it uses static char and snprintf, thus, rsnd_mod_name() user should use it immediately, and shouldn't keep its pointer.
