[PATCH] scsi: fix uninitialized variable in iscsi

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

 



[Resend to get through vger's filters, sorry]

drivers/scsi/scsi_transport_iscsi.c: In function 'iscsi_add_session':
drivers/scsi/scsi_transport_iscsi.c:704: warning: 'err' may be used uninitialized in this function

Indeed the error path can be taken without err being set.

I don't know if ENOMEM is the proper error code to return.
