Yes. One other solution you could do is:
char buf[80], *p = buf;
buf[0] = '\0';
for (i = 0; i < ARRAY_SIZE(err_msg); i++)
if (stat & (1 << i))
p += scnprintf(p, sizeof(buf) - (p - buf),
" %s", err_msg[i]);
dev_dbg(obj->dev, "%s: da:%08x%s\n", __func__, da, buf);
which means that you're then printing the entire string in one go -
and there's no chance for another message to come in the middle of it.
Note that I've placed the ' ' at the beginning of the format string so
that we don't end up with useless trailing space in messages. Minor
point but it's easy to do here.
