Browse Source 
This patch fixes coding style issues reported by checkpatch concerning
to switch case statements. There are few additional changes made to fix
other coding styles issues.

These additional changes are:

 - The compound statement "({...})" on line 474 is pulled out from
   snprintf parameters.

 - On line 723 the constant "0x03" is moved to right.
