Re: [PATCH 2/7] net: ircomm, cleanup TIOCGSERIAL

From: Jiri Slaby <redacted>

In ircomm_tty_get_serial_info, struct serial_struct is memset to 0 and
then some members set to 0 explicitly.

Remove the latter as it is obviously superfluous.

And remove the retinfo check against NULL. copy_to_user will take care
of that.

Part of hub6 cleanup series.
