Protect d_subdirs and d_child with d_lock, except in filesystems that aren't
using dcache_lock for these anyway (eg. using i_mutex).
Note: if we change the locking rule in future so that ->d_child protection is
provided only with ->d_parent->d_lock, it may allow us to reduce some locking.
But it would be an exception to an otherwise regular locking scheme, so we'd
have to see some good results. Probably not worthwhile.

A race exists when initializing ueagle-atm devices where the generic atm
device may not yet be created before the driver attempts to initialize
it's PHY signal state, which checks whether the atm device has been
created or not. This often causes the sysfs 'carrier' attribute to be
'1' even though no signal has actually been found.
uea_probe
usbatm_usb_probe
driver->bind (uea_bind)
uea_boot
kthread_run(uea_kthread) uea_kthread
usbatm_atm_init uea_start_reset
atm_dev_register UPDATE_ATM_SIGNAL
UPDATE_ATM_SIGNAL checks whether the ATM device has been created and if
not, will not update the PHY signal state. Because of the race that
does not always happen in time, and the PHY signal state remains
ATM_PHY_SIG_FOUND even though no signal exists.
To fix the race, just create the kthread during initialization, and only
after initialization is complete, start the thread that reboots the
device and initializes PHY state.

flush_scheduled_work() is being deprecated. Directly flush or cancel
work items instead.
* u_ether, isp1301_omap, speedtch conversions are straight-forward.
* ochi-hcd should only flush when quirk_nec() is true as otherwise the
work wouldn't have been initialized.
* In oti6858, cancel_delayed_work() + flush_scheduled_work() ->
cancel_delayed_work_sync().

Needed to update to apply fixes for which the old branch was too
outdated.
So far the USBLED driver only supports Delcom's "USB Visual Signal
Indicator" (http://www.delcomproducts.com/products_USBLMP.asp). The
driver generates virtual files "red", "green", and "blue" under the
device's /sys/ directory, where color values can be read from and
written to.
This patch adds support for Dream Cheeky's "DL100B Webmail Notifier"
(http://www.dreamcheeky.com/webmail-notifier -- available from several
shops, such as http://www.conrad.at/ce/de/product/777048/USB-WEBMAIL).
This device isn't as pretty as Delcom's, but it's *far* cheaper, and
its 3 LEDs can be set in 32 brightness steps each. The grey envelope
contour can easily be removed, leaving a rather neutral white box (with
a few small holes), which is useful for generic signalling purposes.
Of course, the small circuit board can easily be put into a prettier
case.
The DL100B device pretends to be a HID, but the HID descriptor shows
that it's not overly useful as such (see below). The patch therefore
removes the "HID-ness" (hid-core.c, hid-ids.h), and adds the necessary
commands to usbled.c. The protocol info comes from the developer's
manual that Dream Cheeky kindly provided (815DeveloperManual.pdf).
