2.6.18-git9

[Andy Whitcroft <apw@shadowen.org>]

I have a couple of power boxes which no longer seem to be able to
compile mainline as of 2.6.18-git9.  The build fails as below:

  CC      drivers/usb/core/driver.o
drivers/usb/core/driver.c: In function `usb_probe_device':
drivers/usb/core/driver.c:168: error: structure has no member named
`pm_usage_cnt'
drivers/usb/core/driver.c: In function `usb_driver_claim_interface':
drivers/usb/core/driver.c:305: error: structure has no member named
`pm_mutex'
drivers/usb/core/driver.c:309: error: structure has no member named
`pm_mutex'
drivers/usb/core/driver.c: In function `usb_driver_release_interface':
drivers/usb/core/driver.c:358: error: structure has no member named
`pm_mutex'
drivers/usb/core/driver.c:362: error: structure has no member named
`pm_mutex'
make[3]: *** [drivers/usb/core/driver.o] Error 1
make[2]: *** [drivers/usb/core] Error 2
make[1]: *** [drivers/usb] Error 2
make: *** [drivers] Error 2

This seems to be realated to the changes in this commit:

	commit 645daaab0b6adc35c1838df2a82f9d729fdb1767
    	usbcore: add autosuspend/autoresume infrastructure

The machines in question do not have CONFIG_PM set.  It seems that the
definition of pm_mutex et al in struct usb_device are contingent on that
defined, but the use of it in usb_driver_release_interface() are not.

Its not clear to me if suspending in this context is quite the same as
full suspend to disk that I associate with PM so I am unsure which bit
is in error.  Will retest with those references under CONFIG_PM.

Alan?
