[PATCH] ASoC: codecs: fs210x: fix possible buffer overflow

["Alexander A. Klimov" <grandmaster@al2klimov.de>]

In fs210x_effect_scene_info(), a string was copied like this:

     strscpy(DST, SRC, strlen(SRC));

A buffer overflow would happen if strlen(SRC) > sizeof(DST).
Actually, strscpy() must be used this way:

     strscpy(DST, SRC, sizeof(DST));
     strscpy(DST, SRC); // defaults to sizeof(DST)

Fixes: 756117701779 ("ASoC: codecs: Add FourSemi FS2104/5S audio amplifier driver")
