I have some questions about this patch. Where did you get the information needed
to make these changes? Did it come from reverse engineering some Broadcom code,
or did you look at their actual code? There is a great deal of difference
relative to our "clean-room" status. Anyone that has seen non-GPL Broadcom
material cannot contribute code to b43.
Have you tested this code on devices with rev>=16?
Now for some comments: This patch also needs the "b43:" added to the subject. In
addition, you appear to have at least one white-space error in the
MODULE_FIRMWARE line. Is the addition of your copyright to the driver warranted
by this change? For example, I have made much larger contributions to b43 over
the years before I started doing reverse-engineering on this driver, but I never
added my copyright. Your "Signed-off-by" implies copyright for the patch.
