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

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

From: Dominik Brodowski <linux@dominikbrodowski.net>

commit b83156b52dd77979cc93bafc2283929532f6f7d0 upstream.

Commit a8408c17 introduced a new check to pccard_validate_cis(),
which avoids any "late" calls to this function. This broke the
insertion of cards which require a CIS override which changes
the number of card functions. Fix this by asserting that this
is _not_ a late call, but a proper call early during the card
insertion process.

Fixes https://bugzilla.kernel.org/show_bug.cgi?id=16138
