All whitespace and formatting.  Nothing interesting to see here.  About
the only thing to remember is that we aren't supposed to initialize
static variables to 0/NULL.  It is done for us and doing it ourselves
puts them in a different section.

With this patch running checkpatch.pl against hooks.c only gives us
complaints about busting the 80 character limit and declaring extern's
in .c files.  Apparently they don't like it, but I don't feel like going
to the trouble of moving those to .h files...
