This patch (as1200) finishes some fixes that were left incomplete by
an earlier patch.

Although nobody has addressed this issue in the past, it turns out
that we need to distinguish between two different modes of disabling
and enabling endpoints.  In one mode only the data structures in
usbcore are affected, and in the other mode the host controller and
device hardware states are affected as well.

The earlier patch added an extra argument to the routines in the
enable_endpoint pathways to reflect this difference.  This patch adds
corresponding arguments to the disable_endpoint pathways.  Without
this change, the endpoint toggle state can get out of sync between
the host and the device.  The exact mechanism depends on the details
of the host controller (whether or not it stores its own copy of the
toggle values).

This adds the vendor/product ID of the fasttrax GPS evaluation kit from:
	http://www.fastraxgps.com/products/evaluationtools/evaluationkit/

to the cp2101 module since this device is actually equipped with a
CP210x USB to serial bridge.

The vendor/product ID is: 0x10c4/0x826b.

commit 77ecaf2d ("gianfar: Fix VLAN
HW feature related frame/buffer size calculation") wrongly removed
priv->vlgrp assignment, and now priv->vlgrp is always NULL.

This patch fixes the issue, plus fixes following sparse warning
introduced by the same commit:
gianfar.c:1406:13: warning: context imbalance in 'gfar_vlan_rx_register' - wrong count at exit

gfar_vlan_rx_register() checks for "if (old_grp == grp)" and tries
to return w/o dropping the lock.

According to net/8021q/vlan.c VLAN core issues rx_register() callback:
1. In register_vlan_dev() only on a newly created group;
2. In unregister_vlan_dev() only if the group becomes empty.

Thus the check in the gianfar driver isn't needed.

In previous kernels, any kernel module could get access to the
'real-device' and the VLAN-ID for a particular VLAN.  In more recent
kernels, the code was restructured such that this is hard to do
without accessing private .h files for any module that cannot use
GPL-only symbols.

Attached is a patch to once again allow non-GPL modules the ability to
access the real-device and VLAN id for VLANs.

The current tx_has_work waited until all packets sent by the driver
are marked as completed by the FW. This is too greedy and it causes
the bnx2x_poll to spin in vain. The driver should only check that all
packets FW already completed are freed - only in unload flow the
driver should make sure that transmit queue is empty

If userspace supplies an invalid pointer to a read() of an inotify
instance, the inotify device's event list mutex is unlocked twice.
This causes an unbalance which effectively leaves the data structure
unprotected, and we can trigger oopses by accessing the inotify
instance from different tasks concurrently.

The best fix (contributed largely by Linus) is a total rewrite
of the function in question:
