Ignoring the simple bits to make fw->data const? See
http://git.infradead.org/users/dwmw2/firmware-2.6.git?a=shortlog&h=d71792ac
or    git-diff --stat 59890f74..d71792ac | grep -v firmware/

21 drivers, mostly older USB drivers and including four sound drivers
which were already using request_firmware() optionally. The HEAD of my
tree contains a few more updates in drivers/scsi and drivers/net, but
out of respect for Dave's and Jeff's objections I left those out of the
pull request for now. Hopefully the noise will die down when the sky
doesn't _actually_ fall on our heads, and we can merge the remaining
changes into 2.6.28.
