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.

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.

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).

In order to read/write to the i.MX OTG viewport register it is necessary to setup
the PORTSCx register first.
By default i.MX OTG port is configured for USB serial PHY. In order to use a ULPI PHY
the PORTSCx register needs to be configured properly.
commit 724c852 (USB: ehci/mxc: compile fix) placed the PORTSC setup after the OTG
viewport is accessed and this causes ULPI read/write to fail.
Revert the PORTSC setup order.

CI13xxx UDC driver doesn't call complete() callback for requests
with flag no_interrupt set. Thus gadget drivers (like g_ether) are
never notifed about successfully (or not) transmitted requests. As
a result in case of g_ether and queued request with no_interrupt=1
fields g_ether is never notifed about sent packets and TX stalls.
Solution: treat no_interrupt flag like all other UDC drivers do and
call complete() callback for all requests.

There is one nasty scenario when CI13xxx driver fails:
a) two or more rx requests are queued (g_ether does that)
b) rx request completed, interrupt fires and ci13xxx dequeues rq
c) request complete() callback gets called and in turn it calls ep_queue()
c1) in ep_queue() request gets added to the TAIL of the rx queue list
d) ep gets primed with rq from (b)
e) interrupt fires
f) request gets popped from queue head for hw dequeue
G) requets from queue head wasn't enqueued
g1) isr_tr_complete_low() doesn't
enqueue more requests and it doesn't prime EP,
rx traffic stalls
Solution:
a) enque queued requests ASAP, i.e. before calling complete() callback.
b) don't HW enqueue and prime endpoint with recently added request and
use the oldest request in the queue.
Fixed issues:
a) ep_queue() may return an error code despite request was successfully
added to the queue (if _hardware_enqueue() fails)
b) Added requests are always processed in LIFO order, even if they are
added in complete() callback
c) Finally more than two and more queued requests are processed consistently,
even if they were added in complete() callback
The fix was successfully tested on MIPS based SoC with 4KEc CPU core and
CI13612 USB core. Board successfully boots with NFS root using g_ether
on ci13xxx udc.

This patch fixes an issue where the driver does not handle out data in
setup transactions.
The per endpoint cached status register is cleared in the
pch_udc_svc_control_out function. When there is out data available the
function pch_udc_svc_data_out is called which tries to pick it up the
status, which now is cleared to 0. When the status is 0, the function
doesn't start reading the data from the FIFO.
There is a second bug in all this, pch_udc_svc_data_out takes the
endpoint number (0 for EP0), while pch_udc_svc_control_out passes the
endpoint index (1 for EP0). Effectively pch_udc_svc_data_out picks up
the wrong internal ep structure.
This patch makes sure to put back the cached status and pass the
endpoint number rather than index when calling pch_udc_svc_data_out.
