[v2] raw/ifpga_rawdev: fix fd leak in rte fpga do pr
Checks
Commit Message
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")

Li Qiang <liq3ea@163.com> proposed the same patch.
Why he is not referenced here?
Which patch should I merge?
Hi Thomas,
My patch is the same as LI Qiang's patch.
I was told that Qiang's patch cannot get onto the patchwork, so I just help him do this.

Hi Thomas,
Qian has some problem with his email. So some patch can't be found in patch work.
For it's a urgent bug. After we have aligned with Qian, Andy send this patch. Thanks.

When you need to re-send a patch, please apply it with "git am"
so the original author is kept.
Another nit: the title is full of abbreviation, it is hard to read.
The title prefix should be "raw/ifpga", even if checkpatch complains.
Please re-send, thanks.

Hi,
I saw Qiang's patch on patchwork today,
[v3] drivers: ifpga_rawdev: fix fd leak in rte_fpga_do_pr
So I think it seems OK to ignore my patch.
