"LINUX_VERSION_CODE" is not defined with latest rawhide sync

[Dwaine Garden]

I'm getting the following error with my driver.

In file included from /usr/src/cvsfiles/usbvision/src/usbvision.c:323:
/usr/src/cvsfiles/usbvision/src/i2c-algo-usb.h:57:5: warning: 
"LINUX_VERSION_CODE" is not defined

I can't track down the change to "version.h".   Does anyone know what 
the new macro has changed to?
