Kbuild reported the following error:
All error/warnings (new ones prefixed by >>):
In file included from <command-line>:32:0:
./usr/include/scsi/fc/fc_els.h: In function 'fc_tlv_next_desc':
>> ./usr/include/scsi/fc/fc_els.h:274:4: error: implicit declaration of
function 'be32_to_cpu'; did you mean '__be32_to_cpu'?
[-Werror=implicit-function-declaration]
(be32_to_cpu((tlv)->desc_len) + FC_TLV_DESC_HDR_SZ)
^
>> ./usr/include/scsi/fc/fc_els.h:286:17: note: in expansion of macro
'FC_TLV_DESC_SZ_FROM_LENGTH'
return (desc + FC_TLV_DESC_SZ_FROM_LENGTH(tlv));
^~~~~~~~~~~~~~~~~~~~~~~~~~
cc1: some warnings being treated as errors
Fix by converting fc_tlv_next_desc to use __be32_to_cpu().
