Jing Huang acdc79a60c [SCSI] bfa: fix comments for header files
This patch addresses the comments from Randy Dunlap (Randy.Dunlap@oracle.com)
regarding comment blocks that begining with "/**". bfa driver comments
currently do not follow kernel-doc convention, we hence replace all
/** with /* and **/ with */.
