lightnvm: remove unused rq parameter of nvme_nvm_rqtocmd() to kill warning
With gcc 4.1.2:
drivers/nvme/host/lightnvm.c: In function ‘nvme_nvm_submit_io’:
drivers/nvme/host/lightnvm.c:498: warning: ‘rq’ is used uninitialized in this function
Indeed, since commit 2e13f33a2464fc3a ("lightnvm: create cmd before
allocating request"), the request is passed to nvme_nvm_rqtocmd() before
it is allocated.
Fortunately, as of commit 91276162de9476b8 ("lightnvm: refactor end_io
functions for sync"), nvme_nvm_rqtocmd () no longer uses the passed
request, so this warning is a false positive.
Drop the unused parameter to clean up the code and kill the warning.
Fixes: 2e13f33a2464fc3a ("lightnvm: create cmd before allocating request")
Fixes: 91276162de9476b8 ("lightnvm: refactor end_io functions for sync")
