Subject: RDMA/bnxt: Delete 'nq_ptr' variable which is not used
Patch-mainline: v5.8-rc1
Git-commit: 322f3d45a17f64494152bd5583b68c8855b539c0
References: jsc#SLE-15076
The variable "nq_ptr" is set but never used, this generates the following
warning while compiling kernel with W=1 option.
drivers/infiniband/hw/bnxt_re/qplib_fp.c: In function 'bnxt_qplib_service_nq':
drivers/infiniband/hw/bnxt_re/qplib_fp.c:303:25: warning:
variable 'nq_ptr' set but not used [-Wunused-but-set-variable]
303 | struct nq_base *nqe, **nq_ptr;
|
Fixes: fddcbbb02af4 ("RDMA/bnxt_re: Simplify obtaining queue entry from hw ring")
