6f8aa65b52 USB: add missing KERN_* constants to printks
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.

b6c6393700 Rename WARN() to WARNING() to clear the namespace
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.

0ed930bffa USB: isp116x: fix enumeration on boot
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.

38e2bfc94e USB: Dealias -110 code (more complete)
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.

959eea2191 [PATCH] USB: isp116x-hcd: cleanup
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.

ccdcf77ae3 [PATCH] ISP116x PM updates
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.)

4808a1c026 [PATCH] USB: Add isp116x-hcd USB host controller driver
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.
