According to kerneljanitors todo list all printk calls (beginning
a new line) should have an according KERN_* constant.
Those are the missing peaces here for the usb subsystem.

We want to use WARN() as a variant of WARN_ON(), however a few drivers are
using WARN() internally. This patch renames these to WARNING() to avoid the
namespace clash. A few cases were defining but not using the thing, for those
cases I just deleted the definition.

This patch removes the buffering of the status register.
USB core behavior has changed a bit and this buffering was not refreshed
at the right time. The core got buffered old value of HCRHPORT and it
did not detect any devices on boot.

The purpose of this patch is to split off the case when a device does
not reply on the lower level (which is reported by HC hardware), and
a case when the device accepted the request, but does not reply at
upper level. This redefinition allows to diagnose issues easier,
without asking the user if the -110 happened "immediately".
The usbmon splits such cases already thanks to its timestamp, but
it's not always available.
I adjusted all drivers which I found affected (by searching for "urb").
Out of tree drivers may suffer a little bit, but I do not expect much
breakage. At worst they may print a few messages.

The attached patch makes a cleanup of isp116x-hcd. Most of the volume of
the patch comes from 2 sources: moving the code around to get rid of a
few function prototypes and reworking register dumping functions/macros.
Among other things, switched over from using procfs to debugfs.
Cleanup. The following changes were made:
- Rework register dumping code so it can be used for dumping
to both syslog and debugfs.
- Switch from procfs to debugfs..
- Die gracefully on Unrecoverable Error interrupt.
- Fix memory leak in isp116x_urb_enqueue(), if HC happens to
die in a narrow time window.
- Fix a 'sparce' warning (unnecessary cast).
- Report Devices Removable for root hub ports by default
(was Devices Permanently Attached).
- Move bus suspend/resume functions down in code to get rid of
a few function prototypes.
- A number of one-line cleanups.
- Add an entry to MAINTAINERS.

This makes the isp116x driver stop using usb_suspend_device() and
usb_resume_device() ... usbcore now calls to the root hub methods,
removing the need for this. It also switches from keventd to khubd
for remote wakeup. (Compile tested.)

This patch provides an "isp116x-hcd" driver for Philips'
ISP1160/ISP1161 USB host controllers.
The driver:
- is relatively small, meant for use on embedded platforms.
- runs usbtests 1-14 without problems for days.
- has been in use by 6-7 different people on ARM and PPC platforms,
running a range of devices including USB hubs.
- supports suspend/resume of both the platform device and the root hub;
supports remote wakeup of the root hub (but NOT the platform device)
by USB devices.
- does NOT support ISO transfers (nobody has asked for them).
- is PIO-only.
