Some checkpatch issues were solved by scripts leaving other problems such as alignment and indentation issues. In order to comply with the defined coding style the following fixes were made: - Fixed the function declaration moving the parameters' comments above the function in accordance to the doxygen format. - Fixed functions' opening and closing brackets. These brackets should not be indented. - Fixed the 'if', 'for' and 'while' statements adding the brackets around the sentence. - Fixed comments' alignment. - Fixed indentation. The work was done manually and submitted as one commit. I didn't separate these changes in different commits because they were fixed all at once. Basically, all errors were fixed in every file at once. Change-Id: Icc94a10bfd2cff82007ce60df23b2ccd4c30268d Signed-off-by: Yonattan Louise <yonattan.a.louise.mendoza@intel.com>
