Hello Arushi.

When you do these, please remember to remove the unnecessary
and inconsistent uses of periods and to coalesce formats
where appropriate.

Also, there was _some_ logic here behind the use of the
"cfi_cmdset_0001:" prefix on only some of the error messages.

Perhaps the commit message should describe that change a bit
more fully.

Lastly, please run checkpatch on your proposed patches.
