Subject: [patch] qlcnic: use the correct ring in qlcnic_83xx_process_rcv_ring_diag()
Date: Mon, 27 Jun 2016 23:50:29 +0300	[thread overview]
Message-ID: <20160627205029.GA22095@mwanda> (raw)

There is a static checker warning here "warn: mask and shift to zero"
and the code sets "ring" to zero every time.  From looking at how
QLCNIC_FETCH_RING_ID() is used in qlcnic_83xx_process_rcv_ring() the
qlcnic_83xx_hndl() should be removed.

Fixes: 4be41e92f7c6 ('qlcnic: 83xx data path routines')
Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com>

Not tested.
