The id_table field of the struct usb_device_id is constant in <linux/usb.h>
so it is worth to make the initialization data also constant.
The semantic match that finds this kind of pattern is as follows:

* Remove smp_lock.h from files which don't need it (including some headers!)
* Add smp_lock.h to files which do need it
* Make smp_lock.h include conditional in hardirq.h
It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT
This will make hardirq.h inclusion cheaper for every PREEMPT=n config
(which includes allmodconfig/allyesconfig, BTW)

This patch (as1177) modifies the USB core suspend and resume
routines. The resume functions now will take a pm_message_t argument,
so they will know what sort of resume is occurring. The new argument
is also passed to the port suspend/resume and bus suspend/resume
routines (although they don't use it for anything but debugging).
In addition, special pm_message_t values are used for user-initiated,
device-initiated (i.e., remote wakeup), and automatic suspend/resume.
By testing these values, drivers can tell whether or not a particular
suspend was an autosuspend. Unfortunately, they can't do the same for
resumes -- not until the pm_message_t argument is also passed to the
drivers' resume methods. That will require a bigger change.
IMO, the whole Power Management framework should have been set up this
way in the first place.

USB should not be having it's own printk macros, so remove err() and
use the system-wide standard of dev_err() wherever possible. In the
few places that will not work out, use a basic printk().

* wMaxPacketSize is le16; copying it to a field of local structure and then
using that field as host-endian (size of object to be allocated) is broken.
* bMaxPacketSize0 is 8-bit; feeding it to le16_to_cpu() is bogus and since the
result is used as host-endian, it's not even misspelled cpu_to_le16().
