Please fix the indentation issues above.

move this one row upper.

Please let me know which indentation rule is missed out here. As per 
last
discussion, the parameters on next line should start from open 
parenthesis.
I see the same being followed above.
Also i have been running checkpatch script and it does not show up any 
issue.
Any other script which can be executed to ensure the coding guidelines ?
