oops. sorry about it. I saw all the other messages are having
"i2c-parport: " mentioned. I will modify it. And maybe later I will
send you another patch to use pr_fmt. Or here it may be better if I
mention:
pr_err("i2c-parport: You have chosen not to use parport%d.\n",
port->number);

then what about:
MODULE_PARM_DESC(parport, "Mention number of i2c-parport instances you
want.\n Atmost " __stringify(MAX_DEVICE) " instances are
allowed.\n Mention port numbers you want to use.\n"
" If the port is not to be used mention -1.\n"
" Default is one instance connected to parport0.\n");
