These casts are wrong and unnecessary.  They annoy static checkers
because they imply we are planning to write sizeof(long) bytes to a
sizeof(u32) buffer which would corrupt memory.

Hello Dan,

Can you verify whether that patch is still needed after having applied 
the patch series I posted in July (and that was acknowledged by QLogic): 
http://thread.gmane.org/gmane.linux.scsi/103135 ?

Thanks,

Bart.

Hello Martin,

Do you need more reviews to queue this patch?

It's more than a month old and consequently it doesn't exist :). Please
repost.
