This is because mutexes did not appear until 2.6.16.  There's some macro 
#define cruft in pvrusb2-options.h which is supposed to paste over this 
(by redefining mutex operations in terms of older semaphore operations).  
However DEFINE_MUTEX() wasn't set up there.  Now it is.

I'm test compiling it with every kernel from 2.6.12 up to the present 
before releasing this.  This time.  I meant to do that before (even had 
hundreds of MB of build trees ready) but forgot :-(
