Subject: Remove bogons from the iSeries console
X-Git-Url: http://git.maemo.org/git/?a=commitdiff_plain;h=8bc5fb6abb670fa9079cd1994f016a39f99698fe;p=h-e-n

Remove bogons from the iSeries console

The iSeries driver calls into the n_tty ldisc code directly for some
bizarre reason. I previously tagged this with a query but this actually
does need fixing as n_tty methods when you have a different ldisc set are
not a good thing to call.

In n_tty mode this change should have no effect, the core tty layer has
always called the ldisc ioctl method *anyway* and will call the one for
the right ldisc.
