Subject: [PATCH 0/5] bfa: fix W=1 build warnings

I tried to build an allmodconfig kernel with W=1, and the bfa
driver stuck out for having the most warnings in one file, so
I decided to send patches for all of these and make the driver
build cleanly with the extra warnings enabled.

As most warnings were for functions that lacked a 'static',
I marked them that way, and also used a script to look for
further functions that have a declaration but can also be static.

Overall, this saves around 10% of the size of the driver
module:

   text	   data	    bss	    dec	    hex	filename
 232027	   3012	    976	 236015	  399ef	drivers/scsi/bfa/bfa-before.o
 221851	   2996	    908	 225755	  371db	drivers/scsi/bfa/bfa-after.o

	Arnd

Arnd Bergmann (5):
  bfa: mark symbols static where possible
  bfa: remove unused variables
  bfa: rename some global variables
  bfa: remove unused functions from fbbuild.c
  bfa: remove more unused functions
