[PATCH 53/48] libertas: remove pre_open_check()

[David Woodhouse]

Date: Mon, 10 Dec 2007 15:25:42 -0500

The firmware is always initialised before we register the netdevices.
It's not possible for pre_open_check() to fail.

One day we might try loading firmware in ->open(), but still it won't be
just a _check_, like this.
