[ Upstream commit 566428375a53619196e31803130dd1a7010c4d7f ]
fpga_qpn was assigned but never used and compilation with W=1 produced the following warning:
drivers/net/ethernet/mellanox/mlx5/core/fpga/core.c: In function _mlx5_fpga_event_: drivers/net/ethernet/mellanox/mlx5/core/fpga/core.c:320:6: warning: variable _fpga_qpn_ set but not used [-Wunused-but-set-variable] u32 fpga_qpn; ^~~~~~~~
