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:
