[PATCH] libata: clean up variable name usage in xlat related functions
Variable names in xlat functions are quite confusing now. 'scsicmd' is used for CDB while qc->scsicmd points to struct scsi_cmnd while 'cmd' is used for struct scsi_cmnd. This patch cleans up variable names in xlat functions such that 'scmd' is used for struct scsi_cmnd and 'cdb' for CDB. Also, 'scmd' local variable is added if qc->scsicmd is used multiple times.
