Subject: [195/205] pcmcia: do not initialize the present flag too late.

2.6.34-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Dominik Brodowski <linux@...inikbrodowski.net>

commit e4f1ac2122413736bf2791d3af6533f36b46fc61 upstream.

The "present" flag was initialized too late -- possibly, a card
was already registered at this time, so re-setting the flag to 0
caused pcmcia_dev_present() to fail.
