clang warns:
drivers/scsi/ibmvscsi/ibmvscsi.c:2126:7: warning: variable 'rc' is used
uninitialized whenever switch case is taken [-Wsometimes-uninitialized]
case IBMVSCSI_HOST_ACTION_NONE:
^~~~~~~~~~~~~~~~~~~~~~~~~
drivers/scsi/ibmvscsi/ibmvscsi.c:2151:6: note: uninitialized use occurs
here
if (rc) {
^~
Initialize rc in the IBMVSCSI_HOST_ACTION_UNBLOCK case statement then
shuffle IBMVSCSI_HOST_ACTION_NONE down to the default case statement and
make it return early so that rc is never used uninitialized in this
function.
