[PATCH 0/3] cciss: Fix coccinelle/checkpatch warnings.

[Tobin C. Harding]

Coccinelle warns about unnesesary cast on call to kmalloc(). Checkpatch
emits various warnings when parsing file.

Clean up two checkpatch warnings. Remove trailing whitespace and
clean up opending brace position. Remove unnesesary cast on kmalloc().

[PATCH 2/3] cciss: Fix checkpatch OPEN_BRACE

[Tobin C. Harding]

Checkpatch emits ERROR:OPEN_BRACE: that open brace { should be on the
previous line.

Move open brace to new line. Also add space after if/switch statement
since we introduce more checkpatch errors if not fixed at the same
time.

[PATCH 2/3] cciss: Fix checkpatch OPEN_BRACE

[Tobin C. Harding]

Checkpatch emits ERROR:OPEN_BRACE: that open brace { should be on the
previous line.

Move open brace to new line. Also add space after if/switch statement
since we introduce more checkpatch errors if not fixed at the same
time.
