[PATCH] scsi: lpfc: fix building without debugfs support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



On a randconfig build without CONFIG_SCSI_LPFC_DEBUG_FS, I ran into
multiple compile failures:

drivers/scsi/lpfc/lpfc_debugfs.h: In function 'lpfc_debug_dump_wq':
drivers/scsi/lpfc/lpfc_debugfs.h:405:15: error: 'DUMP_FCP' undeclared (first use in this function); did you mean 'DUMP_VAR'?
drivers/scsi/lpfc/lpfc_debugfs.h:405:15: note: each undeclared identifier is reported only once for each function it appears in
drivers/scsi/lpfc/lpfc_debugfs.h:408:22: error: 'DUMP_NVME' undeclared (first use in this function); did you mean 'DUMP_NONE'?
drivers/scsi/lpfc/lpfc_nvmet.c: In function 'lpfc_nvmet_xmt_ls_rsp_cmp':
drivers/scsi/lpfc/lpfc_nvmet.c:109:2: error: implicit declaration of function 'lpfc_nvmeio_data'; did you mean 'lpfc_mem_free'? [-Werror=implicit-function-declaration]
drivers/scsi/lpfc/lpfc_nvmet.c: In function 'lpfc_nvmet_xmt_fcp_op':
drivers/scsi/lpfc/lpfc_nvmet.c:523:10: error: unused variable 'id' [-Werror=unused-variable]

They are all trivial to fix, so I'm doing it in a combined patch here.

Fixes: 1d9d5a9879ad ("scsi: lpfc: refactor debugfs queue dump routines")
Fixes: bd2cdd5e400f ("scsi: lpfc: NVME Initiator: Add debugfs support")
Fixes: 2b65e18202fd ("scsi: lpfc: NVME Target: Add debugfs support")
