scsi: hisi_sas: Fix type casting and missing static qualifier in debugfs code
Sparse can detect some type casting issues in the debugfs code, so fix it up. Also a missing static qualifier is added to hisi_sas_debugfs_to_reg_name(). Signed-off-by: John Garry <john.garry@huawei.com> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>
