> Subject: [PATCH v2] raw/ifpga_rawdev: fix fd leak in rte fpga do pr
> 
> In rte_fpga_do_pr() function, if 'stat' returns error,
> rte_fpga_do_pr() returns -EINVAL without closing the 'file_fd' that has been
> opened.
> After this patch, 'file_fd' is closed before rte_fpga_do_pr() returns -EINVAL
> when 'stat' returns error
> 
> Coverity issue: 279441
> Fixes: ef1e8ede3da5 ("raw/ifpga: add Intel FPGA bus rawdev driver")
