You said you were compiling 2.6.16-rc4.  What's "linux-2.6.15" doing in 
the path of that suspect header file?  Is this a pure 2.6.16-rc4 source 
tree?

As for that error, while the structure in question is used by 
pvrusb2-audio.c that module makes no attempt to define it.  Try and grep 
your headers for "struct msp_matrix" and see if it really is defined in 
two places.  Another possibility is that the same header is being 
traversed twice in one compilation pass, but kernel headers in my 
experience usually guard against this and there should not have been any 
recent changes in the driver snapshot that might have affected this.  Do 
the problem only happen with this specific driver snapshot?
