Hello All,
Please review this update to the previously submitted megaraid_sas driver.
I have adopted all the feedback received for the initial submission. Since
most of the code is rearranged, I have split the patches into four parts -
the first two remove the original code and the second two add the new code.
Thank you,
Sreenivas Bagalkote

Patch 1 of 4:

As your driver is not in the scsi tree yet please send diff in future that
just apply against the scsi-misc tree. Also please use a mailer that
doesn't mangle the patches.
