The kernel test robot reported the following sparse warning: ".../lpfc_els.c:3984:25: sparse: sparse: cast from restricted __be16" For the error being flagged, using be32_to_cpu() on a be16 data type, it was simple enough. But a review of other elements and warnings were also evaluated. This patch corrected several items in the original patch: - using be32_to_cpu() on a be16 data type - cpu_to_le32 used on a std uint32_t (cpu) data type. Note: this is a bytearray, but stored in le layout by hw at 32bit boundaries. So it possibly needed conversion. - using cpu_to_le32() on a std uint16_t and assigned to a char typeA - using le32_to_cpu on a le16 type - missing cpu_to_le16 on an assignment -- james Fixes: 9064aeb2df8e ("scsi: lpfc: Add EDC ELS support") Reported-by: kernel test robot <lkp@intel.com> Co-developed-by: Justin Tee <justin.tee@broadcom.com> Signed-off-by: Justin Tee <justin.tee@broadcom.com> Signed-off-by: James Smart <jsmart2021@gmail.com> --- drivers/scsi/lpfc/lpfc_els.c | 8 ++++---- drivers/scsi/lpfc/lpfc_hw4.h | 2 +- drivers/scsi/lpfc/lpfc_init.c | 16 ++++++++-------- drivers/scsi/lpfc/lpfc_sli.c | 5 +++-- 4 files changed, 16 insertions(+), 15 deletions(-)
