commit c0ea089dba ("ASoC: rsnd: rsnd_mod_name() handles both name and
ID") merged "name" and "ID" on rsnd_mod_name() to handle sub-ID
(= for CTU/BUSIF).
Then, it decided to share static char to avoid pointless memory.
But, it doesn't work correctry in below case, because last called
name will be used.
dev_xxx(dev, "%s is connected to %s\n",
rsnd_mod_name(mod_a), /* ssiu[00] */
rsnd_mod_name(mod_b)); /* ssi[0] */
->
rcar_sound ec500000.sound: ssi[0] is connected to ssi[0]
~~~~~~ ~~~~~~
We still don't want to have pointless memory, so let's use ring buffer.
16byte x 5 is very enough for this purpose.
dev_xxx(dev, "%s is connected to %s\n",
rsnd_mod_name(mod_a), /* ssiu[00] */
rsnd_mod_name(mod_b)); /* ssi[0] */
->
rcar_sound ec500000.sound: ssiu[00] is connected to ssi[0]
